trpR

Comments [?]

case <OC:Enterobacterales>
Function This protein is an aporepressor. When complexed with L-tryptophan it binds the operator region of the trp operon (5'-ACTAGT-'3') and prevents the initiation of transcription. The complex also regulates trp repressor biosynthesis by binding to its regulatory region.
else
Function This protein is an aporepressor. When complexed with L-tryptophan it binds the operator region of the trp operon and prevents the initiation of transcription.
