Anthranilate synthetase. Some physical and kinetic properties of the enzyme from Serratia marcescens.
Anthranilate synthetase from Serratia marcescens was purified to homogeneity. Criteria for homogeneity were disc gel electrophoresis, sedimentation analysis, and immunodiffusion. During electrofocusing the enzyme was found to have an isoelectric pH of 4.6. Glutamineand ammoniadependent activities superimposed during electrofocusing. Glutamine-dependent activity showed a pH optimum of 7.6, while...
متن کاملChitinases from Serratia marcescens
Serratia marcescens is one of the most effective bacteria for degradation of chitin, a 1,4-β-linked polymer of N-acetyl-β-Dglucosamine (GlcNAc). Chitinolysis by S. marcescens involves at least four enzymes and a chitin-binding protein. Studies of the enzymology and the structures of the enzymes provide insight in how a natural set of chitinolytic enzymes may be built up. S. marcescens chitinase...
متن کاملR factors from Serratia marcescens.
In recent years, Serratia marcescens has become established in certain localities as an agent of hospital infection and cross-infection (Clayton & von Graevenitz, 1966; Wilfert, Barrett & Kass, 1968; Davis, Foltz & Blakemore, 1970; Wilkowske, Washington, Martin & Ritts, 1970). In general, strains of S. marcescens isolated from infective lesions differ from those from other sources in being non-...
متن کاملSerratia marcescens.
Over the last 30 years, Serratia marcescens has become an important cause of nosocomial infection. There have been many reports concerning the identification, antibiotic susceptibility, pathogenicity, epidemiological investigations and typing of this organism. Accurate identification is important in defining outbreaks. The API 20E system has been used widely, but is not individually satisfactor...
متن کاملSerratia marcescens
The nucleotide sequence of the proBA operon from a proline-hyperproducing mutant of Serratia marcescens was determined. Two base substitutions were found: one in theproBstructura1 gene, coding for y-glutamyl kinase (GK), and a second one in the promoter region of the operon. The former base substitution led to a change of the predicted amino acid at position 117 from an alanine to a valine in G...
