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

open access: yesProteins: 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 ...

Gut biogeography of the bacterial microbiota [PDF]

open access: yes, 2016
Animals assemble and maintain a diverse but host-specific gut microbial community. In addition to characteristic microbial compositions along the longitudinal axis of the intestines, discrete bacterial communities form in microhabitats, such as the gut ...

Mucin Type Drives Composition and Mucin Glycan Degradation of an In Vitro Synthetic Microbial Community

open access: yesEnvironmental Microbiology, Volume 28, Issue 5, May 2026.
The human gut outer mucus layer hosts specific microbes. Using a synthetic mucin glycan‐degrading microbial community to mimic this mucosal microbiome, we show that mucin type affects microbial community composition, glycan degradation and metabolite production.

The First Metronidazole-Resistant Bacteroides Species Isolated at Marmara University Hospital: Bacteroides thetaiotaomicron

open access: yesMikrobiyoloji Bulteni, 2013
Bacteroides species, the predominant constituents of the human intestinal microbiota can cause serious intraabdominal and postoperative wound infections and bacteremia. Moreover, these bacteria are more resistant to antimicrobial agents than the other anaerobes.

Metabolite dependence of antibiotic susceptibility in a gut microbe

open access: yesmSphere
Antibiotics save lives but can have unwanted effects on our gut microbes, thereby contributing to disease. A mechanistic understanding of how such microbes respond to antibiotics is hence critical. Recently in mSphere, Nilson et al.

Bacteroides fragilis metabolises exopolysaccharides produced by bifidobacteria [PDF]

open access: yes, 2016
BACKGROUND: Bacteroides fragilis is the most frequent species at the human intestinal mucosal surface, it contributes to the maturation of the immune system although is also considered as an opportunistic pathogen.

Identification and characterization of a glycosulfatase-encoding gene cluster in Bifidobacterium breve UCC2003 [PDF]

open access: yes, 2016
Bifidobacteria constitute a specific group of commensal bacteria, typically found in the gastrointestinal tract (GIT) of humans and other mammals. Bifidobacterium breve strains are numerically prevalent among the gut microbiota of many healthy breast-fed

The NAD(P)H-dependent glutamate dehydrogenase activities of Prevotella ruminicola B(1)4 can be attributed to one enzyme (GdhA), and gdhA expression is regulated in response to the nitrogen source available for growth [PDF]

open access: yes, 1996
Prevotella ruminicola B(1)4 possesses both NADPH- and NADH-linked glutamate dehydrogenase (GDH) activities, with the greatest specific activity being measured from ammonia-limited cultures, Relative to cells grown in the presence of 1 mM ammonium ...

Unveiling the causal effects of gut microbiome on trimethylamine N-oxide: evidence from Mendelian randomization

open access: yesFrontiers in Microbiology
ObjectiveThe relationship between gut microbiome and trimethylamine oxide (TMAO) has not been fully elucidated. We aimed to assess the causal effects of different gut microbes on TMAO using Mendelian randomization (MR).MethodsGut microbiome and TMAO ...
