Glycoside Hydrolases Family 4; GlvA- and pagL-like glycosidases; Bacillus subtilis GlvA and Clostridium acetobutylicum pagL are 6-phospho-alpha-glucosidase, catalyzing the hydrolysis of alpha-glucopyranoside bonds to release glucose from oligosaccharides. The substrate specificities of other members of this subgroup are unknown. Some bacteria simultaneously translocate and phosphorylate disaccharides via the phosphoenolpyruvate-dependent phosphotransferase system (PEP_PTS). After translocation, these phospho-disaccharides may be hydrolyzed by the GH4 glycoside hydrolases, which include 6-phospho-beta-glucosidases, 6-phospho-alpha-glucosidases, alpha-glucosidases/alpha-glucuronidases (only from Thermotoga), and alpha-galactosidases. Members of this subfamily are part of the NAD(P)-binding Rossmann fold superfamily, which includes a wide variety of protein families including the NAD(P)-binding domains of alcohol dehydrogenases, tyrosine-dependent oxidoreductases, glyceraldehyde-3-phosphate dehydrogenases, formate/glycerate dehydrogenases, siroheme synthases, 6-phosphogluconate dehydrogenases, aminoacid dehydrogenases, repressor rex, and NAD-binding potassium channel domains, among others.

Glycoside Hydrases Family 4; Glycoside hydrolases cleave glycosidic bonds to release smaller sugars from oligo- or polysaccharides. Some bacteria simultaneously translocate and phosphorylate disaccharides via the phosphoenolpyruvate-dependent phosphotransferase system (PEP-PTS). After translocation, these phospho-disaccharides may be hydrolyzed by GH4 glycoside hydrolases. Other organisms (such as archaea and Thermotoga maritima) lack the PEP-PTS system, but have several enzymes normally associated with the PEP-PTS operon. GH4 family members include 6-phospho-beta-glucosidases, 6-phospho-alpha-glucosidases, alpha-glucosidases/alpha-glucuronidases (only from Thermotoga), and alpha-galactosidases. They require two cofactors, NAD+ and a divalent metal (Mn2+, Ni2+, Mg2+), for activity. Some also require reducing conditions. GH4 glycoside hydrolases are part of the NAD(P)-binding Rossmann fold superfamily, which includes a wide variety of protein families including the NAD(P)-binding domains of alcohol dehydrogenases, tyrosine-dependent oxidoreductases, glyceraldehyde-3-phosphate dehydrogenases, formate/glycerate dehydrogenases, siroheme synthases, 6-phosphogluconate dehydrogenases, aminoacid dehydrogenases, repressor rex, and NAD-binding potassium channel domains, among others.

After translocation, these phospho-disaccharides may be hydrolyzed by the GH4 glycoside hydrolases such as the phospho-beta-glucosidases. Other organisms (such as archaea and Thermotoga maritima ) lack the PEP-PTS system, but have several enzymes normally associated with the PEP-PTS operon. The 6-phospho-beta-glucosidase from Thermotoga maritima hydrolylzes cellobiose 6-phosphate (6P) into glucose-6P and glucose, in an NAD+ and Mn2+ dependent fashion. The Escherichia coli 6-phospho-beta-glucosidase (also called celF) hydrolyzes a variety of phospho-beta-glucosides including cellobiose-6P, salicin-6P, arbutin-6P, and gentobiose-6P. Phospho-beta-glucosidases are part of the NAD(P)-binding Rossmann fold superfamily, which includes a wide variety of protein families including the NAD(P)-binding domains of alcohol dehydrogenases, tyrosine-dependent oxidoreductases, glyceraldehyde-3-phosphate dehydrogenases, formate/glycerate dehydrogenases, siroheme synthases, 6-phosphogluconate dehydrogenases, aminoacid dehydrogenases, repressor rex, and NAD-binding potassium channel domains, among others.

Glycoside Hydrolases Family 4; Alpha-glucosidases and alpha-galactosidases; Glucosidases cleave glycosidic bonds to release glucose from oligosaccharides.

NAD-dependent, lactate dehydrogenase-like, 2-hydroxycarboxylate dehydrogenase family; Members of this family include ubiquitous enzymes like L-lactate dehydrogenases (LDH), L-2-hydroxyisocaproate dehydrogenases, and some malate dehydrogenases (MDH). LDH catalyzes the last step of glycolysis in which pyruvate is converted to L-lactate. MDH is one of the key enzymes in the citric acid cycle, facilitating both the conversion of malate to oxaloacetate and replenishing levels of oxalacetate by reductive carboxylation of pyruvate. The LDH/MDH-like proteins are part of the NAD(P)-binding Rossmann fold superfamily, which includes a wide variety of protein families including the NAD(P)-binding domains of alcohol dehydrogenases, tyrosine-dependent oxidoreductases, glyceraldehyde-3-phosphate dehydrogenases, formate/glycerate dehydrogenases, siroheme synthases, 6-phosphogluconate dehydrogenases, aminoacid dehydrogenases, repressor rex, and NAD-binding potassium channel domains, among others.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.

Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.

(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
the domain superfamily to which the specific and non-specific hits belong
