Arabinosyltransferase is involved in arabinogalactan (AG) biosynthesis pathway in mycobacteria. AG is a component of the macromolecular assembly of the mycolyl-AG-peptidoglycan complex of the cell wall. This enzyme has important clinical applications as it is believed to be the target of the antimycobacterial drug Ethambutol [1].	Domain

Arabinosyltransferase is involved in arabinogalactan (AG) biosynthesis pathway in mycobacteria. AG is a component of the macromolecular assembly of the mycolyl-AG-peptidoglycan complex of the cell wall. This enzyme has important clinical applications as it is believed to be the target of the antimycobacterial drug Ethambutol [1]. This domain represents the C-terminal extracellular domain that is likely to bind to carbohydrate [2].	Domain

A 4'-phosphopantetheine prosthetic group is attached through a serine. This prosthetic group acts as a a 'swinging arm' for the attachment of activated fatty acid and amino-acid groups. This domain forms a four helix bundle. This family includes members not included in Prosite. The inclusion of these members is supported by sequence analysis and functional evidence. The related domain of Swiss:P19828 has the attachment serine replaced by an alanine.	Domain
