Characterization of a membrane toxin‐antitoxin system, tsaAT, from Staphylococcus aureus

The FEBS Journal, Volume 291, Issue 22, Page 5015-5036, November 2024.
Bacterial toxin‐antitoxin (TA) systems are comprised of a toxin that inhibits essential cellular functions and its cognate antitoxin that neutralizes the toxicity. Here, we show that Staphylococcus aureus TA system, TsaA/TsaT, uniquely consists of two membrane proteins and the TsaT overexpression disrupts membrane integrity in Escherichia coli and S ...

The dual role of a novel Sinorhizobium meliloti chemotaxis protein CheT in signal termination and adaptation

Molecular Microbiology, Volume 122, Issue 4, Page 429-446, October 2024.
Until now, signal termination in Sinorhizobium meliloti involved retrophosphorylation from CheY2~P to CheA and the spontaneous dephosphorylation of CheY1~P. We discovered a novel chemotaxis protein CheT, that acts as a phosphatase for the response regulator CheY1.

DNA Packaging Specificity in the λ‐Like Phages: Gifsy‐1

Molecular Microbiology, Volume 122, Issue 4, Page 491-503, October 2024.
Dimeric λ TerS and chimera transition points. The N‐termini of each TerS derives from a λ‐like source phage: Gifsy‐1, 21, and N15 (labeled arrows). The N‐terminus includes the winged‐helix‐turn‐helix (HTH) DNA‐binding motif that confers the source phage's DNA packaging specificity.

Glycolanguage of the oral microbiota

Molecular Oral Microbiology, Volume 39, Issue 5, Page 291-320, October 2024.
Oral bacteria speak a sophisticated glycolanguage transmitted through versatile glycoinfrastructure, carbohydrate‐active enzymes, and lectins, which contributes decisively to their success in the oral habitat. Deciphering this glycolanguage opens new avenues for novel antibacterials to treat oral diseases. Abstract The oral cavity harbors a diverse and

Comparison of gal–lac operons in wild-type galactose-positive and -negative Streptococcus thermophilus by genomics and transcription analysis

Journal of Industrial Microbiology and Biotechnology, 2019
Abstract Streptococcus thermophilus is one of the most important homo-fermentative thermophilic bacteria, which is widely used as a starter culture in dairy industry. Both wild-type galactose-negative (Gal−) S. thermophilus AR333 and galactose-positive (Gal+) S.
