WebJan 1, 1999 · Abstract. Background: Angiotensin II (Ang II) plays a critical role in the pathophysiology of myocardial ischemia–reperfusion injury. We have recently shown tha WebCysteme synthase, the key enzyme for fixation of inorganic sulfide, catalyses the formation of cysteine from O-acetylserine and inorganic sulfide. Here we report the cloning of cDNAs encoding cysteine synthase isoforms from Arabidopsis thaliana.
WebThe final step of cysteine biosynthesis is the reaction incorporating sulphide moiety into β-position of alanine. The amino acid moiety is derived from serine through O -acetyl-L-serine. Serine acetyltransferase and cysteine synthase ( O -acetylserine (thiol)-lyase) are committed in this final step of cysteine biosynthesis. WebApr 25, 2024 · In higher plants, multiple copies of the cysteine synthase gene are present for cysteine biosynthesis. Some of these genes also have the potential to produce various kinds of β-substitute alanine. In the present study, we cloned a 1275-bp cDNA for cytosolic O-acetylserine(thiol)lyase (cysteine synthase) (Cy-OASTL) from Leucaena …
