nucleotide-binding domain (NBD) of the cell shape-determining proteins MreB, Mbl, MreBH and similar proteins; MreB proteins are bacterial actin homologs that may play a role in cell shape determination by positioning the cell wall synthetic machinery. MreB has also been implicated in chromosome segregation; specifically, MreB is thought to bind to and segregate the replication origin of bacterial chromosomes. The family includes three MreB isoforms, MreB (also called actin-like MreB protein or rod shape-determining protein MreB), Mbl (also called actin-like Mbl protein or rod shape-determining protein Mbl) and MreBH (also called actin-like MreBH protein or rod shape-determining protein MreBH), in cell morphogenesis of Bacillus subtilis. All isoforms can support rod-shaped cell growth normal conditions. They form membrane-associated dynamic filaments that are essential for cell shape determination. They act by regulating cell wall synthesis and cell elongation, and thus cell shape. The feedback loops between cell geometry and their localizations may maintain elongated cell shape by targeting cell wall growth to regions of negative cell wall curvature. Filaments rotate around the cell circumference in concert with the cell wall synthesis enzymes. The process is driven by the cell wall synthesis machinery and does not depend on their polymerization. They organize peptidoglycan synthesis in the lateral cell wall. MreB, Mbl and MreBH can form a complex. The MreB-like family belongs to the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily, all members of which share a common characteristic five-stranded beta sheet occurring in both the N- and C-terminal domains.

nucleotide-binding domain (NBD) of the HSP70 family; HSP70 (70-kDa heat shock protein) family chaperones assist in protein folding and assembly and can direct incompetent "client" proteins towards degradation. Typically, HSP70s have a nucleotide-binding domain (NBD) and a substrate-binding domain (SBD). The nucleotide sits in a deep cleft formed between the two lobes of the NBD. The two subdomains of each lobe change conformation between ATP-bound, ADP-bound, and nucleotide-free states. ATP binding opens up the substrate-binding site; substrate-binding increases the rate of ATP hydrolysis. HSP70 chaperone activity is regulated by various co-chaperones: J-domain proteins and nucleotide exchange factors (NEFs). Some HSP70 family members are not chaperones but instead, function as NEFs to remove ADP from their HSP70 chaperone partners during the ATP hydrolysis cycle, some may function as both chaperones and NEFs. The HSP70 family belongs to the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily, all members of which share a common characteristic five-stranded beta sheet occurring in both the N- and C-terminal domains.

nucleotide-binding domain (NBD) of Helicobacter pylori exopolyphosphatase/guanosine pentaphosphate phosphohydrolase (HpPPX/GppA) and similar proteins; The PPX/GppA family proteins play essential roles in bacterial survival and metabolism. Guanosine pentaphosphate (pppGpp) phosphohydrolase (GppA; EC 3.6.1.40) plays a key role in (p)ppGpp homeostasis. It specifically catalyzes the conversion of pppGpp to ppGpp (guanosine tetraphosphate). Sharing a similar domain structure, GppA is indistinguishable from exopolyphosphatase (PPX; EC 3.6.1.11), which mediates the metabolism of cellular inorganic polyphosphate. Especially, it is responsible for the maintenance of appropriate levels of cellular inorganic polyphosphate (PolyP). The family corresponds a group of proteins similar to Helicobacter pylori PPX/GppA (HpPPX/GppA). HpPPX/GppA is phylogenetically distant from the Escherichia coli homologs. Unlike E. coli that possesses two homologs, EcGppA and EcPPX, H. pylori encodes only one PPX/GppA homolog, HpPPX/GppA.

nucleotide-binding domain (NBD) of Escherichia coli chaperone proteins DnaK, HscA, HscC and similar proteins; Escherichia coli DnaK, also called heat shock 70 kDa protein/HSP70, plays an essential role in the initiation of phage lambda DNA replication, where it acts in an ATP-dependent fashion with the DnaJ protein to release lambda O and P proteins from the preprimosomal complex. DnaK is also involved in chromosomal DNA replication, possibly through an analogous interaction with the DnaA protein. Moreover, DnaK participates actively in the response to hyperosmotic shock. Escherichia coli HscA, also called Hsc66, acts as a chaperone involved in the maturation of iron-sulfur cluster-containing proteins. It has a low intrinsic ATPase activity which is markedly stimulated by HscB. It is involved in the maturation of IscU. Escherichia coli HscC, also called Hsc62, or YbeW, may act as the chaperone. It has ATPase activity. It cannot be stimulated by DnaJ. The family also includes Saccharomyces cerevisiae stress-seventy subfamily C proteins, Ssc1p (also called import motor subunit, mitochondrial; endonuclease SceI 75 kDa subunit; mtHSP70; ENS1; endonuclease SceI 75 kDa subunit) and Ssc3p (also called extracellular mutant protein 10/Ecm10), and Saccharomyces cerevisiae Stress-seventy subfamily Q protein 1/Ssq1p (also called Ssc2p; Ssh1p; mtHSP70 homolog). They all belong to the heat shock protein 70 (HSP70) family of chaperones that assist in protein folding and assembly, and can direct incompetent "client" proteins towards degradation. Typically, HSP70s have a nucleotide-binding domain (NBD) and a substrate-binding domain (SBD). The nucleotide sits in a deep cleft formed between the two lobes of the NBD. The two subdomains of each lobe change conformation between ATP-bound, ADP-bound, and nucleotide-free states. ATP binding opens up the substrate-binding site; substrate-binding increases the rate of ATP hydrolysis. Hsp70 chaperone activity is regulated by various co-chaperones: J-domain proteins and nucleotide exchange factors (NEFs); for Escherichia coli DnaK, these are the DnaJ and GrpE, respectively.

It has a low intrinsic ATPase activity which is markedly stimulated by HscB. It is involved in the maturation of IscU. Members in this subfamily belong to the heat shock protein 70 (HSP70) family of chaperones that assist in protein folding and assembly and can direct incompetent "client" proteins towards degradation. Typically, HSP70s have a nucleotide-binding domain (NBD) and a substrate-binding domain (SBD). The nucleotide sits in a deep cleft formed between the two lobes of the NBD. The two subdomains of each lobe change conformation between ATP-bound, ADP-bound, and nucleotide-free states. ATP binding opens up the substrate-binding site; substrate-binding increases the rate of ATP hydrolysis. HSP70 chaperone activity is regulated by various co-chaperones: J-domain proteins and nucleotide exchange factors (NEFs). HscA's partner J-domain protein is HscB; it does not appear to require a NEF and has been shown to be induced by cold-shock. The HscA-HscB chaperone/co-chaperone pair is involved in [Fe-S] cluster assembly. Pssm-ID: 466834 [Multi-domain] Cd Length: 367 Bit Score: 39.89 E-value: 2.29e-03

nucleotide-binding domain (NBD) of the plasmid segregation protein ParM-like domain family; ParM is a plasmid-encoded bacterial homolog of actin, which polymerizes into filaments similar to F-actin, and plays a vital role in plasmid segregation. ParM filaments segregate plasmids paired at midcell into the individual daughter cells. This subfamily also contains Thermoplasma acidophilum Ta0583, an active ATPase at physiological temperatures, which has a propensity to form filaments. ParM-like proteins belong to the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily of phosphotransferases, all members of which share a common characteristic five-stranded beta sheet occurring in both the N- and C-terminal domains.

nucleotide-binding domain (NBD) of Escherichia coli plasmid segregation protein ParM and similar proteins from ParM domain family; Type II plasmid partition systems utilize ParM NTPases in coordination with a centromere-binding protein called ParR to mediate accurate DNA segregation, a process critical for plasmid retention. The family corresponds to a group of uncharacterized proteins similar to Escherichia coli ParM, also called ParA locus 36 kDa protein, or protein StbA. It is a plasmid-encoded protein involved in the control of plasmid partition and required for accurate segregation of low-copy-number plasmid R1.

nucleotide-binding domain (NBD) of rhamnulokinase (RhaB) and similar proteins; Rhamnulokinase (EC 2.7.1.5), also known as L-rhamnulose kinase, ATP:L-rhamnulose phosphotransferase, L-rhamnulose 1-kinase, or rhamnulose kinase, is an enzyme involved in the second step in rhamnose catabolism. It catalyzes the ATP-dependent phosphorylation of L-rhamnulose to produce L-rhamnulose-1-phosphate and ADP. Rhamnulokinase exists as a monomer composed of two large domains. The ATP binding site is located in the cleft between the two domains. This model includes both the N-terminal domain, which adopts a ribonuclease H-like fold, and the structurally related C-terminal domain. The presence of divalent Mg2+ or Mn2+ is required for catalysis. The subfamily also includes Streptococcus pneumoniae L-fuculose k fuculose Kinase inase (FcsK) that uses ATP to phosphorylate fuculose creating fuculose-1-phosphate, and Alkalihalobacillus clausii bifunctional enzyme RhaA/RhaB. Members of this subfamily belong to the FGGY family of carbohydrate kinases. Pssm-ID: 466791 [Multi-domain] Cd Length: 460 Bit Score: 38.28 E-value: 9.33e-03
