Conservation and Redundancy of Serine Acetyltransferases

Abstract

In the final stages of inorganic sulfur assimilation, plants fix sulfur into Cys, the major intermediate for the formation of sulfur-containing compounds in the cell (reviewed in [Saito, 2004][1]). Two enzymes catalyze the last steps of Cys formation, Ser acetyltransferase (SERAT) and OAS (thiol)
