Features of the shuttle pair 11β-hydroxyprogesterone-11- ketoprogesterone
11β-hydroxyprogesterone (HOP) and 11-ketoprogesterone (KP) are reversible components of a shuttle pair whose interconversion in rat liver is catalyzed by isoform-1 of 11β-hydroxysteroid dehydrogenase. Kidneys also produce this interconversion. The present study was carried out to investigate the shu...
