Cellular and Structural Basis of Synthesis of the Unique Intermediate Dehydro-F 420 -0 in Mycobacteria

Le résumé fourni par la source

Mycobacteria are major environmental microorganisms and cause many significant diseases, including tuberculosis. Mycobacteria make an unusual vitamin-like compound, F 420 , and use it to both persist during stress and resist antibiotic treatment. Understanding how mycobacteria make F 420 is important, as this process can be targeted to create new drugs to combat infections like tuberculosis. In this study, we show that mycobacteria make F 420 in a way that is different from other bacteria. We studied the molecular machinery that mycobacteria use to make F 420 , determining the chemical mechanism for this process and identifying a novel chemical intermediate. These findings also have clinical relevance, given that two new prodrugs for tuberculosis treatment are activated by F 420 .
