Transcription is a vital process in bacterial cell, where genetic information in DNA is transcribed to RNA for the translation of proteins that perform cellular function. Hence, transcription serves as a promising target to develop new antibiotics because inhibition the transcription process should effectively kill the bacteria. Bacterial RNA Polymerase, the core enzyme for transcription, must load the DNA and separate the double-stranded DNA to single stranded DNA to read the genetic information to initiate transcription. This process is also called DNA melting and is facilitated by the opening and c
