CRYSTAL STRUCTURE OF ALR0975
Overview
Phytochelatin synthase (PCS) is a key enzyme for heavy-metal, detoxification in plants. PCS catalyzes the production of glutathione, (GSH)-derived peptides (called phytochelatins or PCs) that bind, heavy-metal ions before vacuolar sequestration. The enzyme can also, hydrolyze GSH and GS-conjugated xenobiotics. In the cyanobacterium Nostoc, the enzyme (NsPCS) contains only the catalytic domain of the eukaryotic, synthase and can act as a GSH hydrolase and weakly as a peptide ligase., The crystal structure of NsPCS in its native form solved at a 2.0-A, resolution shows that NsPCS is a dimer that belongs to the papain, superfamily of cysteine proteases, with a conserved catalytic machinery., Moreover, the structure of the protein solved as a complex with GSH at a, 1.4-A resolution reveals a ...
