Cysteine desulfurase reaction meaning
In enzymology, a cysteine desulfurase (EC 2.8.1.7) is an enzyme that catalyzes the chemical reaction L-cysteine + [enzyme]-cysteine L-alanine + [enzyme]-S-sulfanylcysteine Thus, the two substrates of this enzyme are L-cysteine and [enzyme]-cysteine], whereas its two products are L-alanine and [enzyme]-S-sulfanylcysteine. This enzyme belongs to the family of transferases, specifically the sulfur… In enzymology, a cysteine desulfurase (EC 2.8.1.7) is an enzyme that catalyzes the chemical reaction L-cysteine + [enzyme]-cysteine L-alanine + [enzyme]-S-sulfanylcysteine Thus, the two substrates of this enzyme are L-cysteine and [enzyme]-cysteine], whereas its two products are L-alanine and [enzyme]-S-sulfanylcysteine.
