Glycosyltransferase 34 (IPR008630)

Short name: Glyco_trans_34

Overlapping homologous superfamilies


Family relationships



This family represents a group of glycosyltransferases from plants and fungi, including Mnn10/Mnn11 from budding yeasts, Gma12/Gmh1-3 from fission yeasts and xyloglucan 6-xylosyltransferase 1/2 (XXT1/XXT2) from Arabidopsis.

Mnn10 and Mnn11 are subunits of a Golgi mannosyltransferase complex, which mediates elongation of the polysaccharide mannan backbone [PMID: 10037752].

Gma12 is involved in the O- and N-linked oligosaccharide modification of proteins transported through the Golgi stack, while Gmh3 is involved in the galactosylation of the N-linked core oligosaccharide Man9GlcNAc2 [PMID: 9839953].

XXT1 and XXT2 are xylosyltransferases specific to UDP-D-xylose that accepts both cellopentaose and cellohexaose as substrates, with a better use of cellohexaose, to produce xyloglucan [PMID: 18544630].
