Gene Name:moaE
Enzyme Class:
Biological Properties
General Function:Involved in Mo-molybdopterin cofactor biosynthetic process
Specific Function:Converts molybdopterin precursor Z to molybdopterin. This requires the incorporation of two sulfur atoms into precursor Z to generate a dithiolene group. The sulfur is provided by moaD
