Trehalose Is Required for Growth of Mycobacterium smegmatis*□S
Mycobacteria contain high levels of the disaccharide trehalose in free form as well as within various immunologically relevant glycolipids such as cord factor and sulfolipid-1. By contrast, most bacteria use trehalose solely as a general osmoprotectant or thermoprotectant. Mycobacterium tuberculosis and Mycobacterium smegmatis possess three pathways for the synthesis of trehalose. Most bacteria...

متن کاملCell wall structure of a mutant of Mycobacterium smegmatis defective in the biosynthesis of mycolic acids.
A mutant strain of Mycobacterium smegmatis defective in the biosynthesis of mycolic acids was recently isolated (Liu, J., and Nikaido, H. (1999) Proc. Natl. Acad. Sci. U. S. A. 96, 4011-4016). This mutant failed to synthesize full-length mycolic acids and accumulated a series of long chain beta-hydroxymeromycolates. In this work, we provide a detailed characterization of the localization of mer...
متن کاملGenes required for intrinsic multidrug resistance in Mycobacterium avium.
Genes required for intrinsic multidrug resistance by Mycobacterium avium were identified by screening a library of transposon insertion mutants for the inability to grow in the presence of ciprofloxacin, clarithromycin, and penicillin at subinhibitory concentrations. Two genes, pks12 and Maa2520, were disrupted in multiple drug-susceptible mutants. The pks12 gene (Maa1979), which may be cotrans...
