Pcyd: A promoter open in aerobic conditions

This is an aerobically initiated promoter that initiates transcription of subsequent sequences under microaerobic and aerobic conditions. The mechanism is based on the fact that Fnr takes over the promoter sequence under anaerobic conditions, competes with RNA polymerase for binding sites, and thus prevents the transcription of subsequent sequences. However, under microaerobic and aerobic conditions, Fnr protein does not bind to the sequence, and thus can continue the subsequent transcription.
