The tyrr regulon
WebThe TyrR protein, which can function both as a dimer and as a hexamer, regulates the expression of nine genes constituting the TyrR regulon. TyrR can bind each of the three aromatic amino acids and ATP and under their influence can act as a repressor or activator of gene expression. WebDec 1, 1995 · The Escherichia coli regulatory protein TyrR controls the expression of eight transcription units that encode proteins involved in the biosynthesis and transport of aromatic amino acids. It is a homodimer of 57 600 subunit molecular weight and has a binding site for ATP and weak ATPase activity.
