An Extracellular Nuclease from Serratia marcescens
The specificity of an extracellular nuclease from Serraiia marcescens was examined with both RNA and DNA as substrates. The enzyme was found to act in a predominantly endonucleolytic manner with less than 2% of the degradation products being mononucleotides. Both DNA and RNA were degraded to di-, tri-, and tetranucleotides terminating in 5’-phosphoryl ends. The enzyme had the unusual property o...
متن کاملDifferential secretion of isoforms of Serratia marcescens extracellular nuclease.
Extracellular secretion of the Serratia marcescens nuclease occurs in a two-step process: (i) rapidly to the periplasm via a signal sequence-dependent pathway and then (ii) slowly to the extracellular growth medium without cell lysis. There are two major isoforms of the nuclease in the culture supernatant of S. marcescens. We have isolated, purified, and determined the sequences of both isoform...
متن کاملTransductional construction of a threonine-producing strain of Serratia marcescens.
A threonine-producing strain of Serratia marcescens Sr41 was constructed according to the following process. Thr- strain E-60 was derived from strain HNr59 having constitutive levels of threonine-sensitive aspartokinase and homoserine dehydrogenase. Thr+ transductant T-570 was constructed from strain E-60 and phage grown on strain HNr21 having feedback-resistant threonine-sensitive aspartokinas...

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...
