Figure 7. Summary of transcription initiation at gyr and rrn promoters from M. tuberculosis and M. smegmatis.

Figure 7

Individual equilibrium and kinetic events occurring at M. tuberculosis and M. smegmatis gyr and rrn promoters are compared. RPc and RPo refer to closed complex and open complex respectively, RPI refers to initiation complex, iNTPs refers to initiating nucleotides, PC refers to promoter clearance. iNTPs enhance the formation of RPI at PgyrB1 and stability of open complex at rrn promoters.
