EVIDENCE FOR A TRICARBOXYLIC ACID CYCLE IN SERRATIA MARCESCENS

Evidence for a tricarboxylic acid cycle in Serratia marcescens.

Wrede and Rothhaas (1934) proposed a tripyrrylmethene structure for the red pigment extracted from Serratia marcescens. This structure was supported by Hubbard and Rimington (1950) because of the similarity in spectral properties between extracted pigment and a synthetic tripyrrylmethene compound. Recent investigations (Williams et al., 1956) have demonstrated that pigment identical in spectral...

Tricarboxylic Acid Cycle in

Serratia 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...

Serratia 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...
