An ancestral dual function of OmpM as outer membrane tether and nutrient uptake channel in diderm Firmicutes

A. Silale, Y. Zhu, J. Witwinowski, R. E. Smith, K. E. Newman, S. P. Bhamidimarri, A. Basle, S. Khalid, C. BELOIN, S. Gribaldo, B. van den Berg

This study identifies OmpM as a dual-function protein in diderm Firmicutes that tethers the outer membrane to peptidoglycan and facilitates nutrient uptake.

An ancient divide in outer membrane tethering systems in Bacteria

J. Witwinowski, A. Sartori-Rupp, N. Taib, N. Pende, T. N. Tham, D. Poppleton, J.-M. Ghigo, C. Beloin, S. Gribaldo

The paper investigates the evolution of outer membrane tethering systems in bacteria, showing a bimodal distribution linked to phylogeny and proposing a mechanism for the loss of the outer membrane in Gram-positive bacteria.
