Molecular cloning, expression, and analysis of the genes of the homoprotocatechuate catabolic pathway of Escherichia coli C
J Bacteriol.
1988 Nov.
Abstract
The molecular cloning and fine-structure analysis of the homoprotocatechuate (hpc) catabolic pathway genes of Escherichia coli C are described. The genes were located in two operons, hpcBCDEF and hpcGH, that were very closely linked. A regulatory gene, hpcR, involved in the expression of both operons was also identified. Various subclones isolated in the study were useful in the production of chemical intermediates of the pathway. The availability of one such compound facilitated the discovery of a previously unrecognized isomerase involved in the catabolic sequence.
