Distribution and activity of nitrate and nitrite reductases in the microbiota of the human intestinal tract

The FEBS Journal, EarlyView.
Nitrate from food is first converted to nitrite by oral bacteria and then further processed in the intestine. The gut microbiota reduces nitrate and nitrite to ammonia or nitric oxide, preventing the formation of carcinogenic nitrosamines. Our analysis highlights Escherichia coli as a key player in this detoxification process, supported by other ...

Crystal structure of plant γ‐glutamyl peptidase 1: implications for sulfur metabolism and secondary metabolite biosynthesis

The FEBS Journal, EarlyView.
The crystal structures of Arabidopsis thaliana γ‐glutamyl peptidase 1 (GGP1), including the covalent intermediate state, were determined. GGP1 is involved in both glutathione degradation in the primary metabolism and glutathione conjugate processing in the secondary metabolism of glucosinolate and camalexin biosynthesis.

A distinct sortase SrtB anchors and processes a streptococcal adhesin AbpA with a novel structural property. [PDF]

, 2016
Surface display of proteins by sortases in Gram-positive bacteria is crucial for bacterial fitness and virulence. We found a unique gene locus encoding an amylase-binding adhesin AbpA and a sortase B in oral streptococci.

Antimicrobial peptide GH12 suppresses cariogenic virulence factors of Streptococcus mutans

Journal of Oral Microbiology, 2018
Cariogenic virulence factors of Streptococcus mutans include acidogenicity, aciduricity, and extracellular polysaccharides (EPS) synthesis. The de novo designed antimicrobial peptide GH12 has shown bactericidal effects on S.
