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 ...

Effect of Anabaena sp. PCC7120 on the Tolerance of Rice ( Oryza sativa L. cv Maratelli) Seedlings Against Lindane

Land Degradation &Development, Volume 37, Issue 7, Page 2873-2885, 30 April 2026.
ABSTRACT Lindane (γ‐hexachlorocyclohexane, γ‐HCH) is a broad‐spectrum pesticide widely used since the 1950s until its inclusion in the Stockholm Convention list of Persistent Organic Pollutants (POPs) in 2009, together with other HCH isomers. The high persistence and mismanagement of the toxic wastes generated during its synthesis have led to serious ...

In-situ determination of the mechanical properties of gliding or non-motile bacteria by atomic force microscopy under physiological conditions without immobilization. [PDF]

PLoS ONE, 2013
We present a study about AFM imaging of living, moving or self-immobilized bacteria in their genuine physiological liquid medium. No external immobilization protocol, neither chemical nor mechanical, was needed.

Form species Nostoc commune (Cyanobacteria). [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2001
The form species concept for the Cyanobacteria was evaluated using a comprehensive set of Nostoc samples that were collected during the past two centuries, from all continents, including regions from the Tropics to the Poles. Phylogenies were constructed based upon the conserved regions of tRNALeu (UAA) group I intron DNA sequences.

Toward Sustainability: Intensification of Light‐Driven Whole Cell Biocatalysis

ChemBioChem, Volume 27, Issue 8, April 2026.
Whole‐cell, light‐driven biotransformations in photoautotrophic microorganisms offer the potential for higher atom economy by directly harnessing reducing equivalents and oxygen generated through natural photosynthesis. Current advances include the development of strains with improved growth rates and reactor designs that mitigate self‐shading ...
