LYSOGENY AND LYSOSENSITIVITY IN SALMONELLA STRAINS

Agricultura, 2017
Bacteriophages are viruses pathogenic to bacteria, that is, “bacteria eaters”. The results of the activity of the phage to bacterial cells manifests itself through the following phenomena: (a) The bacterial cell is lysosensitive (it allows the phage to ...

Investigating the molecular mechanisms underlying the anti‐CRISPR function of AcrIIA13b protein

The FEBS Journal, EarlyView.
Anti‐CRISPR protein AcrIIA13b inhibits CRISPR–Cas9 function by preventing target DNA engagement. The Cas9–sgRNA ribonucleoprotein (RNP) normally recognizes the protospacer adjacent motif (PAM) duplex to initiate DNA cleavage. AcrIIA13b binding to the PAM‐interacting WED–PI domain blocks this recognition, leaving the target DNA intact.

Molecular prediction of lytic vs lysogenic states for Microcystis phage: Metatranscriptomic evidence of lysogeny during large bloom events.

PLoS ONE, 2017
Microcystis aeruginosa is a freshwater bloom-forming cyanobacterium capable of producing the potent hepatotoxin, microcystin. Despite increased interest in this organism, little is known about the viruses that infect it and drive nutrient mobilization ...

Enterocinogeny and Lysogeny in Enterococci

Journal of Applied Bacteriology, 1970
Summary. The enterocinogeny and lysogeny of enterococci was studied with a double layer agar method and 21 indicator strains of enterococci. Of 77 strains examined, 76 produced enterocine, and of 19 strains examined, 5 were sensitive to their own enterocine.

Expanding the substrate scope of a bacterial monoterpene synthase for the production of sesquiterpenoid and diterpenoid products

The FEBS Journal, EarlyView.
We have converted the only known true bacterial monoterpene synthase, cineole synthase from Streptomyces clavuligerus (bCinS, C10 substrate), to a highly competent sesquiterpene synthase (C15) with a minimum number of rational mutations. By comparison with diterpene synthases (C20), we were then able to bestow diterpene synthase activity on bCinS. This

High Incidence of Lysogeny in the Oxygen Minimum Zones of the Arabian Sea (Southwest Coast of India)

Viruses, 2018
Though microbial processes in the oxygen minimum zones (OMZs) of the Arabian Sea (AS) are well documented, prokaryote-virus interactions are less known.

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.

Insights into the Functions of a Prophage Recombination Directionality Factor

Viruses, 2012
Recombination directionality factors (RDFs), or excisionases, are essential players of prophage excisive recombination. Despite the essentially catalytic role of the integrase in both integrative and excisive recombination, RDFs are required to direct ...

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

The FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

The FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized
