Role of a major outer membrane protein in Escherichia coli.
Mutants of Escherichia coli B/r lacking a major outer membrane protein, protein b, were obtained by selecting for resistance to copper. These mutants showed a decreased ability to utilize a variety of metabolites when the metabolites were present at low concentrations. Also, mutants of E. coli K-12 lacking proteins b and c from the outer membrane were shown to have an identical defect in the up...
متن کاملPrimary structure of major outer membrane protein II (ompA protein) of Escherichia coli K-12.
The amino acid sequence of major outer membrane protein II (ompA protein) from Escherichia coli K-12 has been determined. The transmembrane polypeptide consists of 325 residues, resulting in a molecular weight of 35,159. The transmembrane part of the protein is located between residues 1 and 177. In this part of the protein a predominantly lipophilic 27-residue segment exists that perhaps spans...
متن کاملEnzyme III stimulation of cyclic AMP synthesis in an Escherichia coli crp mutant.
Cyclic AMP (cAMP) synthesis in Escherichia coli is altered in cAMP receptor protein mutants and in phosphoenolpyruvate:sugar phosphotransferase transport system mutants. The stimulation of cAMP synthesis observed in cAMP receptor protein-deficient mutants is largely dependent upon enzyme III of the phosphoenolpyruvate:sugar phosphotransferase transport system. The phosphoenolpyruvate:sugar phos...
متن کاملRegulation of ribosomal protein synthesis in Escherichia coli.
The kinetics of synthesis of ribosomal, nonribosomal, and total protein, and of ribosomal ribonucleic acid (RNA), were measured in Escherichia coli during a shift-up involving a doubling of specific growth rate. The increase in ribosomal protein synthesis was not accompanied by a corresponding decrease in non-ribosomal protein synthesis. Thus, the average rate of protein synthesis per ribosome ...
متن کاملRegulation of ribosomal protein synthesis in Escherichia coli B/r.
The differential synthesis rate of ribosomal protein (r-protein), alpha-r (synthesis rate of r-protein divided by synthesis rate of total protein), was measured during the cell division cycle. It was observed that alpha-r remained essentially constant and was not measurably affected by duplication of the r-protein gene cluster (i.e., str-spc region) during the process of chromosome replication....
