From :
Transcriptional silencing by the mycobacteriophage L5 repressor
I have verified if the L5 gp71 protein is a protein (183 Aa) with a binding capacity to the DNA.
See:
Helix-turn-helix
Basic-helix-loop-helix
DNA-binding protein
I have used mEMBOSS software (open source)for finding the part of the protein with a binding capacity:
"FNQTEIAELYGVTRQAVSWHKK"

This is the primary and secondary structure of L5 gp 71 repressor:




L5 is a lysogenic mycobacteriophage growing in mycobacteria and for that reason also in M.smegmatis and in M.ulcerans .
The lysogenic cycle is maintained by production of gp71 repressor.
D29 mycobacteriophage does not synthesizes this gp71 repressor
