Identification of SlpB, a Cytotoxic Protease from Serratia marcescens.
The Gram-negative bacterium and opportunistic pathogen Serratia marcescens causes ocular infections in healthy individuals. Secreted protease activity was characterized from 44 ocular clinical isolates, and a higher frequency of protease-positive strains was observed among keratitis isolates than among conjunctivitis isolates. A positive correlation between protease activity and cytotoxicity to...
متن کاملProduction and Characterization of Protease from Serratia marcescens
Extracellular protease produced by Serratia marcescens isolated from the gut of termite (Centrocestus formosanus) was investigated in this study. The effect of temperature, pH, carbon and nitrogen sources on protease production was examined. The extracellular protease was separated from the culture supernatant of the organism through precipitation with ammonium sulfate. The protease was purifie...
متن کاملDifferential effect of Serratia protease on platelet surface glycoproteins Ib and V.
The effect of a zinc metalloprotease from Serratia marcescens on platelet surface glycoproteins (GP) Ib and V was analyzed. Increasing protease treatments caused progressive loss of GP Ib with appearance of the major fragment, glycocalicin, in the supernatant solution. No GP V was detected in the supernatant solution, and protease-pretreated platelets had the same capacity as control platelets ...
متن کاملOrganic solvent tolerant metallo protease of novel isolate Serratia marcescens PPB-26: production and characterization
Proteases are a class of enzymes that catalyze hydrolysis of peptide bonds of proteins. In this study, 221 proteolytic bacterial isolates were obtained by enrichment culture method from soils of various regions of Himachal Pradesh, India. From these a hyper producer of protease was screened and identified by morphological and physiological testing and by 16S rDNA sequence as Serratia marcescens...
متن کاملInterdomain Contacts and the Stability of Serralysin Protease from Serratia marcescens
The serralysin family of bacterial metalloproteases is associated with virulence in multiple modes of infection. These extracellular proteases are members of the Repeats-in-ToXin (RTX) family of toxins and virulence factors, which mediated virulence in E. coli, B. pertussis, and P. aeruginosa, as well as other animal and plant pathogens. The serralysin proteases are structurally dynamic and the...
