Genetic locus (ompB) affecting a major outer-membrane protein in Escherichia coli K-12.
Three multiply colicin-tolerant mutants in Escherichia coli K-12 from the TolIV, TolXIV, and TolXV phenotypic groups, all lacking or having only trace amounts of protein 1, a major outer-membrane protein, were mapped by Hfr crosses, and the position on the chromosome was confirmed by cotransduction with nearby markers. The mutations were located near malQP in the 74-min region of the E. coli ch...
متن کاملA third kasugamycin resistance locus, ksgC, affecting ribosomal protein S2 in Escherichia coli K-12.
A third kasugamycin-resistant mutant affecting ribosomal protein S2 has been isolated from Escherichia coli K-12. Mating and transduction revealed that this newly recognized kasugamycin resistance locus, designated as ksgC, is located at 0.1 to 0.2 min from purE.
متن کاملNew locus for exopolysaccharide overproduction in Escherichia coli K-12.
A new locus for exopolysaccharide overproduction in Escherichia coli K-12 was mapped by insertion mutagenesis. A 66% linkage to serA, which is located at 62 min on the E. coli K-12 linkage map, was shown by P1 transduction. The polysaccharide produced by the mutant was isolated and was shown to be similar to colanic acid.
متن کاملGenetic mapping of the locus for detergent-resistant phospholipase A(pldA) in Escherichia coli K-12.
An Escherichia coli K-12 mutant deficient for detergent-resistant (DR) phospholipase A, a principal enzyme catalyzing the first step in phospholipid degradation, was characterized genetically. The mutation was found to affect the locus pldA (phospholipid degradation), which is cotransducible both with ilv and metE at a frequencies of 13 and 78%, respectively, and shown to lie between the ilv an...
