Thiol-activated hemolysins as virulence markers of bacteria

Publisher:

Committee on Biotechnology PAS ; Institute of Bioorganic Chemistry PAS

Abstract:

The article contains information regarding the similarities and differencesbetween proteins of the thiol-activated cytolysins family (TACY). Members ofthis group of haemolysins are produced by several species of Gram-positive bacteria {Listeria spp., Streptococcus spp., Bacillus spp., Clostridium spp.,) and also byGram-negative Klebsiella spp. Their cytolytic activity is sensitive to oxygen andcan be restored by adding reducing compounds. TACY bind to cholesterol-containing membranes to form pores. Preincubation of the toxin with smallamounts of cholesterol inhibits hemolytic activity as well as cytolysis ofeucaryotic cells. Members ofthe group show 40-70% similarity in amino acid sequence, and contain an almost invariant Trp-rich undecapeptide sequence(ECTGLAWEWWR). The TACY are important virulence factors. Recently increased use has been made of molecular methods (PCR, hybridization) in the detection and identification of the TACY producing bacteria.
