The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 5, Page 1092-1103, May 2026.
ABSTRACT Serine acetyltransferase (CysE) is a member of the left‐handed β‐helix family of acetyltransferases that catalyze the rate limiting step in de novo cysteine biosynthesis. There are two isoforms of CysE that differ in length, with the shorter isoform lacking approximately 76 amino acids at the N‐terminus of the protein from the serine ...

Biogeography of the Purple Nonsulfur Bacterium Rhodopseudomonas palustris [PDF]

Applied and Environmental Microbiology, 2003
ABSTRACT The biogeography of the purple nonsulfur bacterium Rhodopseudomonas palustris on a local scale was investigated. Thirty clones of phototrophic bacteria were isolated from each of five unevenly spaced sampling locations in freshwater marsh sediments along a linear 10-m transect, and a total of 150 ...

The Arsenal of Aromatic Degrading Bacteria: How They Sense, Chase, Adapt and Destroy Environmental Pollutants

Microbial Biotechnology, Volume 19, Issue 5, May 2026.
In the environment, bacteria sense aromatic pollutants, migrate toward them, adapt to toxicity, and deploy specialized uptake and catabolic systems. Genomic plasticity, metabolic versatility and division of labor within populations together aid in the degradation of persistent aromatics, highlights that biodegradation is driven by various eco ...

MicrobeDiscover: A Knowledge Graph–Enabled AI Framework for Identifying Microbes for Inorganic Nanomaterial Biosynthesis

Advanced Science, Volume 13, Issue 20, 9 April 2026.
Microbial synthesis of nanomaterials (NMs) is eco‐friendly, but the screening of microorganisms is limited by inefficient traditional methods (currently only involving∽400 microorganisms/90 NMs). We propose AI framework MicrobeDiscover, integrating a knowledge graph of microbe‐NM interactions.

UPO‐Mimetic Engineering of CYP199A4 Enables Enhanced Peroxygenase Activity via the Hydrogen Peroxide Shunt Pathway

ChemistryEurope, Volume 4, Issue 3, March 2026.
P450 goes peroxide: When one base just isn’t basic enough. Engineering a second basic residue into CYP199A4T252E boosts its peroxygenase activity but also makes it sensitive to H2O2. The double mutant F182R/T252E shows increased turnover before rapidly self‐destructing, revealing the fine balance between productive peroxide activation and oxidative ...
