NCBI Protein Information
Nucleotide-diphospho-sugar transferases superfamily protein
NCBI Summary
The PARVUS/GLZ1 gene encodes a putative family 8 glycosyl transferase that contributes to xylan biosynthesis. Its gene expression shows good co-variance with the IRX3 gene involved in secondary cell wall synthesis. PARVUS/GLZ1 is predicted to have galacturonosyltransferase activity and may be involved in the formation of the complex oligosaccharide sequence present at the reducing end of xylan. PARVUS is expressed in cells undergoing secondary wall thickening, and parvus mutants have thinner cell walls.

UniProt Comments
Required for the biosynthesis of the tetrasaccharide primer sequence, beta-D-Xyl-(1,3)-alpha-l-Rha-(1,2)-alpha-D-GalA-(1,4)-D-Xyl, located at the reducing end of glucuronoxylan. Might catalyze the transfer of the reducing Xyl residue onto a protein acceptor in the endoplasmic reticulum, which is then transported to the Golgi where the subsequent additions of sugar residues take place.
