EC 2.8.1.9 Details

show Brenda entry

EC number

2.8.1.9

Accepted name

molybdenum cofactor sulfurtransferase

Reaction

molybdenum cofactor + L-cysteine + reduced acceptor + 2 H⁺ = thio-molybdenum cofactor + L-alanine + H₂O + oxidized acceptor

Other name(s)

molybdenum cofactor sulfurase, ABA3, HMCS, MoCo sulfurase, MoCo sulfurtransferase

Systematic name

L-cysteine:molybdenum cofactor sulfurtransferase

Comment

Contains pyridoxal phosphate. Replaces the equatorial oxo ligand of the molybdenum by sulfur via an enzyme-bound persulfide. The reaction occurs in prokaryotes and eukaryotes but MoCo sulfurtransferases are only found in eukaryotes. In prokaryotes the reaction is catalysed by two enzymes: cysteine desulfurase (EC 2.8.1.7), which is homologous to the N-terminus of eukaryotic MoCo sulfurtransferases, and a molybdo-enzyme specific chaperone which binds the MoCo and acts as an adapter protein.
