WebFeb 1, 2014 · Cysteine is synthesized during the sulfate assimilation pathway via the incorporation of sulfide to O-acetylserine, catalyzed by O-acetylserine (thiol)lyase (OASTL). Plant cells contain OASTLs in the mitochondria, chloroplasts, and cytosol, resulting in a complex array of isoforms and subcellular cysteine pools. WebMar 4, 2024 · The results show that OsOASTL-A1 functions as a cysteine synthase. OsOASTL-A1 complements the Arabidopsis cysteine synthase mutant. The A. thaliana mutant old3-2/atoastl-a1 carries a homozygous T-DNA insertion in the AtOASTL-A1/OLD3 gene and shows a total loss of the in vitro OASTL activity (Shirzadian-Khorramabad et …
