title: Electrophoresis of NADH-dependent oxidoreductase (diaphorase) in boar spermatozoa.
abstract: Two forms of NADH-dependent oxidoreductase (diaphorase [EC.1.6.99.-]) are established in boar spermatozoa. The first form is typical for soluble proteins with a varying electrophoretic profile, while the other form for sedimental proteins with a specific, slowly-moving fraction, which is not common for the soluble form. The two enzyme forms have a close isoelectric point (pI5.5-6.0) and they can not be inhibited by dicumarol 10(-5) mol l-1 and FAD 10(-4) mol l-1. The molecular mass of the soluble form of the enzyme is 28, 37, 46 and 67 kD, while of the sedimental form it is 220, 250 and 260 kD, respectively.
