Formation of dTDP-Rhamnose Is Essential for Growth of Mycobacteria

Abstract
It was determined that the dTDP-rhamnose synthesis gene, rmlD , could be inactivated in Mycobacterium smegmatis only in the presence of a rescue plasmid carrying functional rmlD. Hence, dTDP-rhamnose biosynthesis is essential for the growth of mycobacteria and the targeting of dTDP-rhamnose synthesis for new tuberculosis drugs is supported.
