Enzymatic properties of mutant Escherichia coli tryptophan synthase alpha-subunits.

The Journal of biological chemistry - 25 Oct 1991

Lim W K, Sarkar S K, Hardman J K

Abstract excerpt

Thirty-nine mutant tryptophan synthase alpha subunits have been purified and analyzed (in the presence of the beta 2-subunit) for their enzymatic (kcat, Km) behavior in the reactions catalyzed by the alpha 2.beta 2 complex, the fully constituted form of this enzyme. The mutant alpha subunits, obt...
