Phosphorylation of VapB antitoxins affects intermolecular interactions to regulate VapC toxin activity in Mycobacterium tuberculosis

B. Malakar, V. Barth, J. Puffal, N. Woychik, R. N. Husson

This study shows that phosphorylation of VapB antitoxins in M. tuberculosis alters their interactions with VapC toxins and promoter DNA, thereby regulating toxin activity and bacterial survival.

Compartmentalized Cell Envelope Biosynthesis in Mycobacterium tuberculosis

J. Puffal, I. L. Sparks, J. R. Brenner, X. Li, J. D. Leszyk, J. Hayashi, S. A. Shaffer, Y. S. Morita

This paper identifies the conserved intracellular membrane domain (IMD) in Mycobacterium tuberculosis, showing it is a specialized compartment for synthesizing virulence-related lipids.

The mycobacterial cell wall partitions the plasma membrane to organize its own synthesis

A. Garcia-Heredia, T. Kado, C. E. Sein, J. Puffal, S. H. Osman, J. Judd, T. A. Gray, Y. S. Morita, M. S. Siegrist

The paper shows that in Mycobacterium smegmatis, peptidoglycan precursors are synthesized in distinct plasma membrane domains that are separate from sites of cell wall assembly, and this partitioning is essential for ordered synthesis.
