Protein
Sialyltransferase-like protein 2
Organism
Arabidopsis thaliana
Function
May be involved in the transfer of 2-keto-3-deoxy-D-lyxo-heptulosaric acid (Dha) and/or 2-keto-3-deoxy-D-manno-octulosonic acid (Kdo) on the homogalacturonan backbone of rhamnogalacturonan-II. Required for efficient pollen grain germination and pollen tube elongation (PubMed:24825296). Does not possess sialyltransferase activity in vitro (PubMed:19470101).
Similarity
Belongs to the glycosyltransferase 29 family.
