IntEnz Enzyme Nomenclature


Accepted name:
3-(methylthio)propionyl—CoA ligase
Other names:
MMPA-CoA ligase
methylmercaptopropionate-coenzyme A ligase
3-methylmercaptopropionyl-CoA ligase
Systematic name:
3-(methylsulfanyl)propanoate:CoA ligase (AMP-forming)




The enzyme is part of a dimethylsulfoniopropanoate demethylation pathway in the marine bacteria Ruegeria pomeroyi and Pelagibacter ubique. It also occurs in some nonmarine bacteria capable of metabolizing dimethylsulfoniopropionate (e.g. Burkholderia thailandensis, Pseudomonas aeruginosa, and Silicibacter lacuscaerulensis). It requires Mg2+ [2].
