title: Purification and characterization of Cob(II)yrinic acid a,c-diamide reductase from Pseudomonas denitrificans.
abstract: An NADH-dependent flavoenzyme exhibiting cob(II)yrinic acid a,c-diamide reductase activity was purified 6,300-fold to homogeneity from Pseudomonas denitrificans and sequenced at its N terminus. This enzyme of the cobalamin biosynthetic pathway reduced to the Co(I) state all of the Co(II)-corrinoids isolated from this microorganism.
