the hybridization results thus demonstrate that ( i ) the regulation of the argecbh gene cluster in e. coli is under transcriptional control , ( ii ) the orientation of transcription is divergent , ( iii ) e gene transcribes anticlockwise , whereas the rest of the genes , c , b , and h , transcribe clockwise , and ( iv ) the position of the promoter ( s ) and operator ( s ) is located between the e and c genes of the argecbh cluster .
