ENZYME entry: EC 2.4.2.61
Accepted Name |
alpha-dystroglycan beta1,4-xylosyltransferase.
|
Reaction catalysed |
3-O-[Rib-ol-P-Rib-ol-P-3-beta-D-GalNAc-(1->3)-beta-D-GlcNAc-(1->4)-(O-6-P-alpha-D-Man)]-Thr-[protein] + UDP-alpha-D-xylose <=> 3-O-[beta-D-Xyl-(1->4)-Rib-ol-P-Rib-ol-P-3-beta-D-GalNAc-(1->3)-beta-D-GlcNAc-(1->4)-(O-6-P-alpha-D-Man)]-Thr-[protein] + H(+) + UDP |
Comment(s) |
- This eukaryotic enzyme catalyzes a step in the biosynthesis of the
glycan moiety of the membrane protein alpha-dystroglycan.
- It is specific for the second ribitol 5-phosphate in the nascent
glycan chain as acceptor.
