Characterization of the plasmidic or chromosomal cpe gene and metabolic activities in Clostridium perfringens isolates from food in San Luis--Argentina.

Cent Eur J Public Health 2011 Mar;19(1):46-53

General Microbiology, Area of Microbiology, Department of Biochemistry and Biological Sciences, Faculty of Chemistry, Biochemistry and Pharmacy, San Luis National University, Argentina.

Food poisoning and non-food poisoning illnesses due to C. perfringens (by enterotoxin production) have been associated to chromosomal or plasmidic location of the cpe gene, respectively. Clostridial pathogenicity has been correlated to protease and azoreductase production. Read More

Enterococcus faecalis virulence regulator FsrA binding to target promoters.

J Bacteriol 2011 Apr 21;193(7):1527-32. Epub 2011 Jan 21.

The Scripps Research Institute, Department of Molecular and Experimental Medicine, Mail Code MEM-116, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.

The FsrABDC signal transduction system is a major virulence regulator in Enterococcus faecalis. The FsrC sensor histidine kinase, upon activation by the gelatinase biosynthesis-activating pheromone (GBAP) peptide encoded by the fsrBD genes, phosphorylates the FsrA response regulator required for the transcription of the fsrBDC and the gelE-sprE genes from the fsrB promoter and the gelE promoter, respectively. FsrA belongs to the LytTR family of proteins, which includes other virulence regulators, such as AgrA of Staphylococcus aureus, AlgR of Pseudomonas aeruginosa, and VirR of Clostridium perfringens.

Clostridium absonum alpha-toxin: new insights into clostridial phospholipase C substrate binding and specificity.

J Mol Biol 2003 Oct;333(4):759-69

School of Crystallography, Birkbeck College, Malet Street, London WC1E 7HX, UK.

Clostridium absonum phospholipase C (Caa) is a 42.7 kDa protein, which shows 60% amino acid sequence identity with the Clostridium perfringens phospholipase C, or alpha-toxin (Cpa), and has been isolated from patients suffering from gas gangrene. We report the cloning and sequencing, purification, characterisation and crystal structure of the Caa enzyme. Read More
