KEGG ENZYME: 2.4.2.62

ENZYME: 2.4.2.62

Entry

EC 2.4.2.62                 Enzyme

Name

xylosyl alpha-1,3-xylosyltransferase;
XXYLT1 (gene name)

Class

Transferases;
Glycosyltransferases;
Pentosyltransferases

Sysname

UDP-alpha-D-xylose:[EGF-like domain protein]-3-O-[alpha-D-xylosyl-(1->3)-beta-D-glucosyl]-L-serine 3-alpha-D-xylosyltransferase (configuration-retaining)

Reaction(IUBMB)

UDP-alpha-D-xylose + [protein with EGF-like domain]-3-O-[alpha-D-xylosyl-(1->3)-beta-D-glucosyl]-L-serine = UDP + [protein with EGF-like domain]-3-O-[alpha-D-xylosyl-(1->3)-alpha-D-xylosyl-(1->3)-beta-D-glucosyl]-L-serine [RN:R12637]

Reaction(KEGG)

R12637(G)

Substrate

UDP-alpha-D-xylose [CPD:C00190];
[protein with EGF-like domain]-3-O-[alpha-D-xylosyl-(1->3)-beta-D-glucosyl]-L-serine

Product

UDP [CPD:C00015];
[protein with EGF-like domain]-3-O-[alpha-D-xylosyl-(1->3)-alpha-D-xylosyl-(1->3)-beta-D-glucosyl]-L-serine

Comment

The enzyme, found in animals and insects, is involved in the biosynthesis of the alpha-D-xylosyl-(1->3)-alpha-D-xylosyl-(1->3)-beta-D-glucosyl trisaccharide on epidermal growth factor-like (EGF-like) domains. When present on Notch proteins, the trisaccharide functions as a modulator of the signalling activity of this protein.
