I9H — Asparagus officinalis

Summary

A4U43_C04F180 (I9H) on asparagus chromosome 4 encodes a protein with glycosyltransferase domains (Glyco_trans_43, Nucleotide-diphossugar_trans) and exhibits xylosyltransferase and galactosylgalactosylxylosylprotein 3-beta-glucuronosyltransferase activities, along with transglycosidase activity and metal binding. The gene is associated with glucuronoxylan and xylan anabolism, secondary cell wall biogenesis, pollen exine formation, and cell wall organization, and its product localizes to the Golgi membrane and Golgi complex. It is also linked to glucuronoxylan biosynthesis.
