Structural and mechanistic comparison of the Cyclopropane Mycolic Acid Synthases (CMAS) protein family of Mycobacterium tuberculosis.

Tuberculosis (TB) is a chronic disease caused by the bacillus Mycobacterium tuberculosis(Mtb) and remains a leading cause of mortality worldwide. The bacteria has an external wall which protects it from being killed, and the enzymes involved in the biosynthesis of the cell wall components have been proposed as promising targets for future drug development efforts. Cyclopropane Mycolic Acid Synthases (CMAS) constitute a group of ten homologous enzymes which belong to the mycolic acid biosynthesis pathway.
