Characterization and Expression Analysis of a Serine Acetytransferase Gene Family Involved in a Key Step of the Sulfur Assimilation Pathway in Arabidopsis

Goulart Kawashima, Cintia; Berkowitz, Oliver; Hell, Ruediger; Noji, Masaaki; Saito, Kazuki

Description

Ser acetyltransferase (SATase; EC 2.3.1.30) catalyzes the formation of O-acetyl-Ser from L-Ser and acetyl-CoA, leading to synthesis of Cys. According to its position at the decisive junction of the pathways of sulfur assimilation and amino acid metabolism, SATases are subject to regulatory mechanisms to control the flux of Cys synthesis. In Arabidopsis (Arabidopsis thaliana) there are five genes encoding SATase-like proteins. Two isoforms, Serat3;1 and Serat3;2, were characterized with respect...[Show more]
