sucrose phosphate synthase/possible sucrose phosphate phosphatase, plant; Members of this family are sucrose-phosphate synthases of plants. This enzyme is known to exist in multigene families in several species of both monocots and dicots. The N-terminal domain is the glucosyltransferase domain. Members of this family also have a variable linker region and a C-terminal domain that resembles sucrose phosphate phosphatase (SPP) (EC 3.1.3.24) (see TIGR01485), the next and final enzyme of sucrose biosynthesis. The SPP-like domain likely serves a binding and not a catalytic function, as the reported SPP is always encoded by a distinct protein. : Pssm-ID: 274147 [Multi-domain] Cd Length: 1050 Bit Score: 2023.16 E-value: 0e+00

sucrose-phosphate synthase; belongs to the haloalcanoic acid dehalogenase (HAD) superfamily; Sucrose phosphate synthase (SPS; EC 2.4.1.14) also known as UDP-glucose-fructose-phosphate glucosyltransferase, catalyzes the transfer of a hexosyl group from UDP-glucose to D-fructose 6-phosphate to form UDP and D-sucrose-6-phosphate, this is the rate limiting step of sucrose synthesis. Members of this family belong to the haloacid dehalogenase-like (HAD) hydrolases, a large superfamily of diverse enzymes that catalyze carbon or phosphoryl group transfer reactions on a range of substrates, using an active site aspartate in nucleophilic catalysis. Members of this superfamily include 2-L-haloalkanoic acid dehalogenase (C-Cl bond hydrolysis), azetidine hydrolase (C-N bond hydrolysis); phosphonoacetaldehyde hydrolase (C-P bond hydrolysis), phosphoserine phosphatase and phosphomannomutase (CO-P bond hydrolysis), P-type ATPases (PO-P bond hydrolysis) and many others. HAD hydrolases are found in all three kingdoms of life, and most genomes are predicted to contain multiple HAD-like proteins. Members possess a highly conserved alpha/beta core domain, and many also possess a small cap domain, the fold and function of which is variable. HAD hydrolases are sometimes referred to as belonging to the DDDD superfamily of phosphohydrolases. Pssm-ID: 319856 Cd Length: 174 Bit Score: 262.56 E-value: 1.35e-81

phosphatidyl-myo-inositol mannosyltransferase; This family is most closely related to the GT4 family of glycosyltransferases and named after PimA in Propionibacterium freudenreichii, which is involved in the biosynthesis of phosphatidyl-myo-inositol mannosides (PIM) which are early precursors in the biosynthesis of lipomannans (LM) and lipoarabinomannans (LAM), and catalyzes the addition of a mannosyl residue from GDP-D-mannose (GDP-Man) to the position 2 of the carrier lipid phosphatidyl-myo-inositol (PI) to generate a phosphatidyl-myo-inositol bearing an alpha-1,2-linked mannose residue (PIM1). Glycosyltransferases catalyze the transfer of sugar moieties from activated donor molecules to specific acceptor molecules, forming glycosidic bonds. The acceptor molecule can be a lipid, a protein, a heterocyclic compound, or another carbohydrate residue. This group of glycosyltransferases is most closely related to the previously defined glycosyltransferase family 1 (GT1). The members of this family may transfer UDP, ADP, GDP, or CMP linked sugars. The diverse enzymatic activities among members of this family reflect a wide range of biological functions. The protein structure available for this family has the GTB topology, one of the two protein topologies observed for nucleotide-sugar-dependent glycosyltransferases. GTB proteins have distinct N- and C- terminal domains each containing a typical Rossmann fold. The two domains have high structural homology despite minimal sequence homology. The large cleft that separates the two domains includes the catalytic center and permits a high degree of flexibility. The members of this family are found mainly in certain bacteria and archaea.

GTB proteins have distinct N- and C- terminal domains each containing a typical Rossmann fold. The two domains have high structural homology despite minimal sequence homology. The large cleft that separates the two domains includes the catalytic center and permits a high degree of flexibility. The members of this family are found mainly in bacteria, while some of them are also found in Archaea and eukaryotes. Pssm-ID: 340859 [Multi-domain] Cd Length: 370 Bit Score: 57.36 E-value: 2.18e-08

glycosyltransferase family 4 proteins; This family is most closely related to the GT4 family of glycosyltransferases. Glycosyltransferases catalyze the transfer of sugar moieties from activated donor molecules to specific acceptor molecules, forming glycosidic bonds. The acceptor molecule can be a lipid, a protein, a heterocyclic compound, or another carbohydrate residue. This group of glycosyltransferases is most closely related to the previously defined glycosyltransferase family 1 (GT1). The members of this family may transfer UDP, ADP, GDP, or CMP linked sugars.

alpha-1,3/1,6-mannosyltransferase ALG2 and similar proteins; This family is most closely related to the GT4 family of glycosyltransferases. ALG2, a 1,3-mannosyltransferase, in yeast catalyzes the mannosylation of Man(2)GlcNAc(2)-dolichol diphosphate and Man(1)GlcNAc(2)-dolichol diphosphate to form Man(3)GlcNAc(2)-dolichol diphosphate. A deficiency of this enzyme causes an abnormal accumulation of Man1GlcNAc2-PP-dolichol and Man2GlcNAc2-PP-dolichol, which is associated with a type of congenital disorders of glycosylation (CDG), designated CDG-Ii, in humans.

phosphatidylinositol N-acetylglucosaminyltransferase subunit A and similar proteins; This family is most closely related to the GT4 family of glycosyltransferases. Phosphatidylinositol glycan-class A (PIG-A), an X-linked gene in humans, is necessary for the synthesis of N-acetylglucosaminyl-phosphatidylinositol, a very early intermediate in glycosyl phosphatidylinositol (GPI)-anchor biosynthesis. The GPI-anchor is an important cellular structure that facilitates the attachment of many proteins to cell surfaces. Somatic mutations in PIG-A have been associated with Paroxysmal Nocturnal Hemoglobinuria (PNH), an acquired hematological disorder.
