IUBMB Comments Involved in the biosynthesis of poly(ribitol-phosphate) teichoic acids in the cell wall of the bacterium Staphylococcus aureus . This enzyme adds an N -acetyl-β-D -glucosamine to the OH group at the 2 position of the ribitol phosphate units. cf . EC 2.4.1.70 [poly(ribitol-phosphate) α-N -acetylglucosaminyltransferase].
The expected taxonomic range for this enzyme is: Staphylococcus aureus
