| Accepted name: |
galactan 5-O-arabinofuranosyltransferase |
| Reaction: |
Adds an α-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 [β-D-galactofuranosyl-(1→5)-β-D-galactofuranosyl-(1→6)]14-β-D-galactofuranosyl-(1→5)-β-D-galactofuranosyl-(1→4)-α-L-rhamnopyranosyl-(1→3)-N-acetyl-α-D-glucosaminyl-diphospho-trans,octacis-decaprenol |

AftA; Rv3792 |
| Systematic name: |
galactofuranan:trans,octacis-decaprenylphospho-β-D-arabinofuranose 5-O-α-D-arabinofuranosyltransferase |
| 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. |
