Ectoine biosynthesis in Mycobacterium smegmatis.

Mycobacterium smegmatis is a commonly used mycobacterial model system. Here, we show that M. smegmatis protects itself against elevated salinity by synthesizing ectoine and hydroxyectoine and characterize the phenotype of a nonproducing mutant. This is the first analysis of M. smegmatis halotolerance and of the molecular mechanism that supports it.

Biosynthesis of ergothioneine from endogenous hercynine in Mycobacterium smegmatis.

Ergothioneine was synthesized and accumulated in growing cultures of Mycobacterium smegmatis when the medium was adequately supplied with sulfur. In a low sulfur medium, the accumulation was sharply limited although growth of the organism was apparently normal. Synthesis of hercynine, the precursor of ergothioneine, was unaffected by low sulfur levels and was markedly increased by addition of l...

Defective mycolic acid biosynthesis in a mutant of Mycobacterium smegmatis.

A mutant of Mycobacterium smegmatis defective in mycolic acid biosynthesis was isolated following chemical mutagenesis. Fatty acids were extracted from the mutant and subjected to structural analysis by thin-layer chromatography and high-performance liquid chromatography (HPLC) of both methyl and p-bromophenacyl ester derivatives. Thin-layer chromatography did not show the presence of any fatty...

MICROBIAL TRANSFORMATION OF CHOLESTEROL BY MYCOBACTERIUM SMEGMATIS

Mycobacterium smegmatis PTCC 1307 (CIP 73.26) was used as a microbial agent to produce androsta-1,4-diene-3,17-dione (ADD) and androst-4-ene-3,17-dione, two useful precursors in the synthesis of steroid drugs. The side chain of cholesterol, as the substrate, was selectively cleaved in the presence of five enzyme inhibitors. An intermediate structure with intact side chain, cholest-4-ene-3-one, ...

MmpS4 promotes glycopeptidolipids biosynthesis and export in Mycobacterium smegmatis.

The MmpS family (mycobacterial membrane protein small) includes over 100 small membrane proteins specific to the genus Mycobacterium that have not yet been studied experimentally. The genes encoding MmpS proteins are often associated with mmpL genes, which are homologous to the RND (resistance nodulation cell division) genes of Gram-negative bacteria that encode proteins functioning as multidru...
