Mitochondrial serine acetyltransferase functions as a pacemaker of cysteine synthesis in plant cells.

Plant physiology - 1 Oct 2008

Haas Florian H, Heeg Corinna, Queiroz Rafael, Bauer Andrea, Wirtz Markus, Hell Rüdiger

Abstract excerpt

Cysteine (Cys) synthesis in plants is carried out by two sequential reactions catalyzed by the rate-limiting enzyme serine acetyltransferase (SAT) and excess amounts of O-acetylserine(thiol)lyase. Why these reactions occur in plastids, mitochondria, and cytosol of plants remained unclear. Expression of artificial microRNA (amiRNA) against Sat3 encoding mitochondrial SAT3 in transgenic Arabidopsis (Arabidopsis...
