The S-adenosylmethionine-dependent enzyme MoaA, in concert with MoaC, catalyzes the first step of molybdenum cofactor biosynthesis, the conversion of guanosine 5'-triphosphate (5'-GTP) into precursor Z. A published X-ray crystal structure of MoaA wit

The presence of nonheme metal, such as copper and iron, in the heme-copper oxidase (HCO) superfamily is critical to the enzymatic activity of reducing O2 to H2O, but the exact mechanism the nonheme metal ion uses to confer and fine-tune the activity
