N-terminal-like domain of Paenibacillus sp. YM-1 Laminaribiose Phosphorylase and similar proteins. The glycoside hydrolase family 94 (previously known as glycosyltransferase family 36) includes bacterial laminaribiose phosphorylase. 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]. Bacterial laminaribiose phosphorylase phosphorolyzes laminaribiose into alpha-glucose 1-phosphate and glucose, but does not phosphorolyze other glucobioses; it slightly phosphorolyzed laminaritriose and higher laminarioligosaccharides. The GH64N domain, as represented by this model, is also found at the N-terminus of GH94 members with uncharacterized specificities.

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.

N-terminal domain of glycoside hydrolase family 94 and related domains. 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]. This GH64N domain also occurs in tandem repeat arrangements (not at the N-terminus) in cyclic beta 1-2 glucan synthetase and related proteins, and as a standalone domain in distantly related proteins of unknown function.

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.
