O-Acetyl-L-serine, a cysteine precursor, is used as a substrate for the identification, differentiation and characterization of O-acetyl-L-serine(thiol)lyase(s) (OASTL) involved in cysteine biosynthesis.
Plant cysteine (Cys) synthesis can occur in three cellular compartments: the chloroplast, cytoplasm, and mitochondrion. Cys formation is catalyzed by the enzyme O-acetylserine(thiol)lyase (OASTL) using O-acetylserine (OAS) and sulfide as substrates. To unravel the function of different isoforms of OASTL

The last steps of cysteine biosynthesis are catalysed by a bi-enzyme complex composed of serine acetyltransferase (SAT) and cysteine synthase, also called O-acetyl-serine (thiol) lyase (OASTL). SAT is responsible for the production of O-acetyl-serine (OAS) from serine and acetyl-coenzyme A
Two low phytic acid (lpa) mutants have been developed previously with the aim to improve the nutritional value of rice (Oryza sativa) grains. In the present study, the impacts of lpa mutations on grain composition and underlying molecular mechanisms were
CysK from Lactobacillus casei encodes a protein with O-acetylserine sulfhydrylase and cysteine desulfurization activity.

We analyzed the effects of deprivation and subsequent restoration of sulphate (S) in the nutrient solution on cysteine (Cys) and O-acetyl-L-serine (OAS) levels in Chlorella sorokiniana (211/8k). The removal of S from the culture medium caused a time-dependent increase in
