Glycosyl hydrolase 36 superfamily, catalytic domain. This is the catalytic region of the superfamily of enzymes referred to as GH36. UniProtKB:Q76IQ9 is a chitobiose phosphorylase that catalyzes the reversible phosphorolysis of chitobiose into alpha-GlcNAc-1-phosphate and GlcNAc with inversion of the anomeric configuration. The full-length enzyme comprises a beta sandwich domain and an (alpha/alpha)(6) barrel domain. The alpha-helical barrel component of the domain, this family, is the catalytic region.

Cellobiose phosphorylase [Carbohydrate transport and metabolism].

N-terminal domain of chitobiose phosphorylase (ChBP) and similar proteins. The glycoside hydrolase family 94 (previously known as glycosyltransferase family 36) includes chitobiose phosphorylase (EC:2.4.1.-). This N-terminal domain is involved in oligomerization and may play a role in catalysis, but it is separate from the catalytic domain [an (alpha/alpha)(6) barrel]. Chitobiose phosphorylase catalyzes the reversible phosphate dependent hydrolysis of chitobiose [(GlcNAc)2] into alpha-GlcNAc-1-phosphate and GlcNAc. In some organisms, ChBP may be involved in the production of GlcNac-6-phosphate in intracellular pathways.

Glycosyltransferase family 36. The glycosyltransferase family 36 includes cellobiose phosphorylase (EC:2.4.1.20), cellodextrin phosphorylase (EC:2.4.1.49), chitobiose phosphorylase (EC:2.4.1.-). Many members of this family contain two copies of this domain.

Glycoside hydrolase family 94 N-terminal-like domain of uncharacterized function. The glycoside hydrolase family 94 (previously known as glycosyltransferase family 36) includes cellobiose phosphorylase (EC:2.4.1.20), cellodextrin phosphorylase (EC:2.4.1.49), chitobiose phosphorylase (EC:2.4.1.-), amongst other members. Their N-terminal domain is involved in oligomerization and may play a role in catalysis, but it is separate from the catalytic domain [an (alpha/alpha)(6) barrel]. The GH64N domain, as represented by this model, is found near the N-terminus of GH94 members and related proteins with uncharacterized specificities.
