Name: tyrR
Synonym(s): OP00096
Gene(s): tyrR   Genome Browser M3D Gene expression COLOMBOS
Note(s): In the regulatory region of the tyrR gene there are two TyrR boxes Cornish EC,1986. Pittard AJ,1991 where the protein appears to bind without a cofactor to autorepress the expression of the gene Camakaris H,1982.
