Mycobacterial cell wall arabinan synthesis protein. 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.

EmbC C-terminal 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. This domain represents the C-terminal extracellular domain that is likely to bind to carbohydrate.

Arabinosyltransferase concanavalin like 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.

Macrolide efflux protein A and similar proteins of the Major Facilitator Superfamily of transporters. This family is composed of Streptococcus pyogenes macrolide efflux protein A (MefA) and similar transporters, many of which remain uncharacterized. Some members may be multidrug resistance (MDR) transporters, which are drug/H+ antiporters (DHAs) that mediate the efflux of a variety of drugs and toxic compounds, conferring resistance to these compounds. MefA confers resistance to 14-membered macrolides including erythromycin and to 15-membered macrolides. It functions as an efflux pump to regulate intracellular macrolide levels. The MefA-like family belongs to the Major Facilitator Superfamily (MFS) of membrane transport proteins, which are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.
