DNA sequence analysis of the dnaK gene of Escherichia coli B and of two dnaK genes carrying the temperature-sensitive mutations dnaK7(Ts) and dnaK756(Ts).

Abstract excerpt

The DNA sequence of the dnaK gene of Escherichia coli was analyzed. The nucleotide sequence of the wild-type dnaK gene of E. coli B differed from that of E. coli K-12 in 15 bp, none of which altered the amino acid sequence. Two temperature-sensitive dnaK mutations were examined by cloning and sequence analyses. Results showed that one dnaK mutation, dnaK7(Ts), was a one-base substitution of T for C at nucleotide...
