Polar allele duplication for transcriptional analysis of consecutive essential genes: application to a cluster of Escherichia coli fatty acid biosynthetic genes.

Abstract excerpt

The genes encoding acyl carrier protein and several key fatty acid biosynthetic enzymes are clustered at min 24 of the Escherichia coli chromosome. This cluster of genes is not transcribed as a classical operon, but rather multiple promoters are present and each gene is cotranscribed with at least one other gene. Transcripts specific for single genes ar also present. Transcription of acpP, the gene encoding acyl...
