Reaction: 2-furoyl-CoA + H2O + acceptor = S-(5-hydroxy-2-furoyl)-CoA + reduced acceptor
Other name(s): furoyl-CoA hydroxylase; 2-furoyl coenzyme A hydroxylase; 2-furoyl coenzyme A dehydrogenase; 2-furoyl-CoA:(acceptor) 5-oxidoreductase (hydroxylating)
Systematic name: 2-furoyl-CoA:acceptor 5-oxidoreductase (hydroxylating)
Comments: A copper protein. The oxygen atom of the -OH produced is derived from water, not O2; the actual oxidative step is probably dehydrogenation of a hydrated form -CHOH-CH2- to -C(OH)=CH-, which tautomerizes non-enzymically to -CO-CH2-, giving (5-oxo-4,5-dihydro-2-furoyl)-CoA. Methylene blue, nitro blue, tetrazolium and a membrane fraction from Pseudomonas putida can act as acceptors.
