Abstract excerpt

Escherichia coli DnaA protein initiates chromosomal replication and is an important regulatory target during the replication cycle. In this study, a suppressor mutation isolated by transposon mutagenesis was found to allow growth of the temperature-sensitive dnaA508 and dnaA167 mutants at 40 degrees C. The suppressor consists of a transposon insertion in a previously annotated ORF, here termed hspQ, a novel heat...
