EC 2.4.2.46 Galactan 5-O-arabinofuranosyltransferase. [-]    

Reaction: Adds an alpha-D-arabinofuranosyl group from trans,octacis- decaprenylphospho-beta-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.
Comments: Isolated from Mycobacterium tuberculosis and Corynebacterium glutamicum. These arabinofuranosyl groups form the start of an arabinofuranan chain as part of the of the cell wall in mycobacteria.
