Cysteine occupies a central position in plant metabolism because it is a reduced sulfur donor moleculeinvolved in the synthesis of essential biomolecules and defense compounds. Moreover, cysteine per se and its deriva...
Triosephosphate isomerase (TPI) catalyzes the interconversion of glyceraldehyde-3-phosphate to dihydroxyacetone phosphate. Photosynthetic organisms generally contain two isoforms of TPI located in both cytoplasm and...
In non-cyanogenic species, the main source of cyanide derives from ethylene and camalexin biosyntheses. In mitochondria, cyanide is a potent inhibitor of the cytochrome c oxidase and is metabolized by the β-cyanoalan...
