Ultrahigh-affinity transport proteins from ubiquitous marine bacteria reveal mechanisms and global patterns of nutrient uptake

B. E. Clifton, U. Alcolombri, C. J. Jackson, P. Laurino

The paper identifies ultrahigh-affinity transport proteins in SAR11 bacteria, revealing their molecular mechanisms and global patterns of nutrient uptake in the ocean.

Bacterial chemotaxis to saccharides is governed by a trade-off between sensing and uptake

N. Norris, U. Alcolombri, J. M. Keegstra, Y. Yawata, F. Menolascina, E. Frazzoli, N. M. Levine, V. I. Fernandez, R. Stocker

This paper shows E. coli limits maltose uptake via porins to enhance chemotactic sensitivity to micromolar maltose gradients despite having a high-affinity transport system.

A redox-regulated type III metacaspase controls cell death in a marine diatom

S. Graff van Creveld, S. Ben-Dor, A. Mizrachi, U. Alcolombri, A. Hopes, T. Mock, S. Rosenwasser, A. Vardi

This study identifies a redox-regulated metacaspase in a marine diatom that promotes cell death and is sensitive to a diatom-specific infochemical.
