Zinc-catalyzed sulfur alkyation:insights from protein farnesyltransferase.

ABSTRACT

Zinc metalloenzymes catalyze many important cellular reactions. Recently, the involvement of zinc in the catalysis of alkylation of sulfur groups has gained prominence. Current studies of the zinc metalloenzyme protein farnesyltransferase have shed light on its structure and catalytic mechanism, as well as the general mechanism of zinc-catalyzed sulfur alkylation.
