Arabinosyltransferase
An arabinosyltransferase is a transferase enzyme acting upon arabinose.
This enzyme is involved in polymerisation of arabinogalactan. Mycobacterially, the more precise term is arabinofuranosyltransferase, since the arabinose residues occur only in a furanose form.
This enzyme has important clinical applications as it is believed to be the target of the antimycobacterial drug Ethambutol.
