COMPARATIVE CHARACTERIZATION OF PORINS FROM SALMONELLA TYPHIO-901 AND SALMONELLA TYPHIMURIUM RA-30
Porins from Salmonella typhi 0-901 and Salmonella typhimurium Ra-30 were characterized and compared. The elution profile of porins from these salmonella species on Sepharose-48 and HPLC appear to be very similar. The findings were confirmed by the electrophoretic pattern which showed three types of porins, i.e. OmpC, OmpD and OmpF in both species. These porins appear to be similar, if not ...
متن کاملLipids of Salmonella typhimurium and Escherichia coli: structure and metabolism.
The nature and quantity of the phospholipids of Salmonella typhimurium and Escherichia coli K-12 have been examined. The main classes of phospholipids, phosphatidylethanolamine, phosphatidylglycerol, and cardiolipin have been completely characterized. Four minor compounds have been detected: phosphatidylserine, phosphatidic acid, and two partially characterized lipids. The phospholipid composit...
متن کاملPeptidases and proteases of Escherichia coli and Salmonella typhimurium.
A number of peptidases and proteases have been identified in Escherichia coli. Although their specific physiological roles are often not known, some of them have been shown to be involved in: the maturation of nascent polypeptide chains; the maturation of protein precursors; the signal peptide processing of exported proteins; the degradation of abnormal proteins; the use of small peptides as nu...
متن کاملGlycerol elicits energy taxis of Escherichia coli and Salmonella typhimurium.
Escherichia coli and Salmonella typhimurium show positive chemotaxis to glycerol, a chemical previously reported to be a repellent for E. coli. The threshold of the attractant response in both species was 10(-6) M glycerol. Glycerol chemotaxis was energy dependent and coincident with an increase in membrane potential. Metabolism of glycerol was required for chemotaxis, and when lactate was pres...
متن کاملThe genetic homology of Salmonella typhimurium and Escherichia coli.
H Y B R I D S of enteric bacteria have been useful for various purposes which include the mapping of regions of the Salmonella typhimurium chromosome which are larger than transducing fragments but too short for convenient timeof-entry mapping (DEMEREC l964,1965a,b; DEMEREC and OHTA 1964; GLATZER, LABRIE and ARMSTRONG 1966; ARMSTRONG 1967). Hybrids have also been employed to determine the genet...
