Galactan 5-O-arabinofuranosyltransferase (, AftA, Rv3792) is an enzyme with systematic name galactofuranan:trans,octacis-decaprenylphospho-beta-D-arabinofuranose 5-O-alpha-D-arabinofuranosyltransferase. This enzyme catalyses the following chemical reaction
: Adds an alpha-D-arabinofuranosyl group from trans,octacis-decaprenylphospho-β-D-arabinofuranose at the 5-O-position of the eighth, tenth and twelfth galactofuranose unit of the galactofuranan chain of [beta-D-galactofuranosyl-(1-5)-beta-D-galactofuranosyl-(1-6)]14-beta-D-galactofuranosyl-(1-5)-beta-D-galactofuranosyl-(1-4)-alpha-L-rhamnopyranosyl-(1-3)-N-acetyl-alpha-D-glucosaminyl-diphospho-trans,octacis-decaprenol
This enzyme is isolated from Mycobacterium tuberculosis and Corynebacterium glutamicum.
