Dominant-negative modification reveals the regulatory function of the multimeric cysteine synthase protein complex in transgenic tobacco.

The Plant cell - 1 Feb 2007

Wirtz Markus, Hell Rüdiger

Abstract excerpt

Cys synthesis in plants constitutes the entry of reduced sulfur from assimilatory sulfate reduction into metabolism. The catalyzing enzymes serine acetyltransferase (SAT) and O-acetylserine (OAS) thiol lyase (OAS-TL) reversibly form the heterooligomeric Cys synthase complex (CSC). Dominant-negative mutation of the CSC showed the crucial function for the regulation of Cys biosynthesis in vivo. An Arabidopsis...
