Purification and characterization of two forms of microsomal carbonyl reductase in guinea pig liver.

Usui, S, Hara, A, Nakayama, T, Sawada, H

Two forms of microsomal carbonyl reductase, solubilized in Triton X-100, were purified to homogeneity from the liver of male guinea pigs, primarily by affinity, DEAE-Sephacel, gel-filtration and...

Guinea-pig liver testosterone 17 beta-dehydrogenase (NADP+) and aldehyde reductase exhibit benzene dihydrodiol dehydrogenase activity.

Hara, A, Hayashibara, M, Nakayama, T, Hasebe, K, Usui, S, Sawada, H

We have kinetically and immunologically demonstrated that testosterone 17 beta-dehydrogenase (NADP+) isoenzymes (EC 1.1.1.64) and aldehyde reductase (EC 1.1.1.2) from guinea-pig liver catalyse the...

Reconstruction of ionic currents in a molluscan photoreceptor.

Sakakibara, M, Ikeno, H, Usui, S, Collin, C, Alkon, D L

Two-microelectrode voltage-clamp measurements were made to determine the kinetics and voltage dependence of ionic currents across the soma membrane of the Hermissenda type B photoreceptor. The...
