Abstract
Transcription of the metA gene of Escherichia coli K-12 is from a promoter which is under methionine control and is located next to a region which has an extensive sequence homology with the operator regions of the metBL and metF genes. However, in the metA gene there is a second transcription start point which is located 74 base pairs upstream and which is independent of the intracellular methionine concentration.
