| Accepted name: |
EGF-domain serine xylosyltransferase |
| Reaction: |
UDP-α-D-xylose + [protein with EGF-like domain]-L-serine = UDP + [protein with EGF-like domain]-3-O-(β-D-xylosyl)-L-serine |
| Other name(s): |
POGLUT1 (gene name) (ambiguous); rumi (gene name) (ambiguous) |
| Systematic name: |
UDP-α-D-xylose:[protein with EGF-like domain]-L-serine O-β-xylosyltransferase (configuration-inverting) |
| Comments: |
The enzyme, found in animals and insects, xylosylates at the serine in the C-X-S-X-P-C motif of epidermal growth factor-like (EGF-like) domains. The enzyme is bifunctional also being active with UDP-α-glucose as donor (EC 2.4.1.376, EGF-domain serine glucosyltransferase). |
