Transcriptome analysis of the progressive adaptation of Lactococcus lactis to carbon starvation.

abstract：:In Escherichia coli, the three branched-chain amino acid activating enzymes appear to be essential for multivalent repression of the isoleucine- and valine-forming enzymes. The results of experiments with a mutant, strain CU18, having an altered threonine deaminase, indicate that free isoleucine and some form of threo...
