However , since operon is differentially expressed under conditions , we hypothesized that FhlA , stimulates transcription from the 54-dependent promoter in the intergenic region between hypO .
However , since the hydrogenase 2 -LRB- hypO-hybABCDE -RRB- is differentially expressed under conditions , we hypothesized that FhlA , stimulates transcription from the 54-dependent promoter in the intergenic region between hypO .
