Enzyme Name (EC)
protein xylosyltransferase (2.4.2.26)
Gene Summary
peptide O-xylosyltransferase (oxt) encodes an enzyme that catalyzes the first xylose of the linkage region of glycosaminoglycan (GAG). Through GAG synthesis, the product of oxt is involved in several signaling pathways mediated by GAGs in development. [Date last reviewed: 2019-03-14] (FlyBase Gene Snapshot)

Gene Group (FlyBase)
XYLOSYLTRANSFERASES -
Xylosyltransferases catalyze the transfer of a xylosyl group to an acceptor molecule, which may be a lipid, carbohydrate, protein or proteoglycan.
Protein Function (UniProtKB)
Catalyzes the first step in biosynthesis of glycosaminoglycan. Transfers D-xylose from UDP-D-xylose to specific serine residues of the core protein. Initial enzyme in the biosynthesis of chondroitin sulfate and dermatan sulfate proteoglycans in fibroblasts and chondrocytes.

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.
