Partial purification and characterization of NADP-dependent 12alpha-hydroxysteroid dehydrogenase from Clostridium leptum.
@article{Harris1978PartialPA, title={Partial purification and characterization of NADP-dependent 12alpha-hydroxysteroid dehydrogenase from Clostridium leptum.}, author={J. Harris and P. Hylemon}, journal={Biochimica et biophysica acta}, year={1978}, volume={528 1}, pages={ 148-57 } }
An NADP-linked 12α-hydroxysteroid dehydrogenase was purified 63-fold from crude extracts (105 000 × g supernatant fraction) of Clostridium leptum using Bio-Gel A-1.5 M and DEAE-cellulose column chromatography. The 63-fold purified enzyme preparation (specific activity 3.3 I.U./mg protein) had a pH optimum of 8.5–9.0. A molecular weight of approx. 225 000 was estimated for the catalytically active enzyme by molecular sieve chromatography. The enzyme converted both unconjugated bile acids as well… CONTINUE READING
