Arabinofuranosyltransferase, N-terminal (IPR007680)

Short name: Arabino_trans_N

Overlapping homologous superfamilies


Domain relationships



Arabinosyltransferases EmbA, EmbB and EmbC are known to be involved in arabinogalactan (AG) and lipoarabinomannan (LAM) biosynthesis in mycobacteria. Synthesis of LAM, but not AG, ceases after inactivation of EmbC, while the arabinan of AG is affected by EmbA or EmbB disruption [PMID: 14507364]. The arabinans of the mycobacterial cell wall are key structural and immunological polymers. These enzymes could have important clinical applications as they are believed to be the target of the antimycobacterial drug Ethambutol [PMID: 8876238].

This entry represents the N-terminal domain found in arabinosyltransferase EmbA, EmbB and EmbC.
