About

Comments (originally from EcoCyc[1][2]) This enzyme catalyzes the first and second steps in the biosynthesis of tyrosine. The enzyme occurs in two aggregation states, a dimer and a tetramer. The tetrameric species is only observed in the presence of the co-factor NAD+ and/or the end product inhibitor tyrosine. [3][4][4]
