Cellobiose phosphorylase [Carbohydrate transport and metabolism].

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.

First GH94N domain of cyclic beta 1-2 glucan synthetase and similar domains. The glycoside hydrolase family 94 (previously known as glycosyltransferase family 36) includes cyclic beta 1-2 glucan synthetase (EC:2.4.1.20) or ChvB (encoded by the chromosomal chvB virulence gene). This first of two tandemly repeated GH94-N-terminal-like domains has not been characterized functionally. Some beta 1-2 glucan synthetases are annotated as NdvB (nodule development B) gene products, glycosyltransferases required for the synthesis of cyclic beta-(1,2)-glucans, which play a role in interactions between bacteria and plants.

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.

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.
