Arabinosyltransferase

In molecular biology, an arabinosyltransferase is a transferase enzyme acting upon arabinose. This enzyme is involved in polymerisation of arabinogalactan (an essential component of the mycobacterial cell wall). Mycobacterially, the more precise term is arabinofuranosyltransferase, since the arabinose residues occur only in a furanose form.
