alanine

This enzyme characterised from Arabidopsis thaliana replaces the equatorial oxygen ligand atom attached to molybdenum by sulfur, which is provided from the amino acid L-cysteine. A reduced electron acceptor is required during the reaction and the enzyme contains pyridoxal phosphate.^[2]^[3]^[4]
