UniProtKB - P82809 (AK1CD_MESAU)
Protein
Aldo-keto reductase family 1 member C13
Gene
AKR1C13
Organism
Mesocricetus auratus (Golden hamster)
Status
Functioni
Catalyzes the dehydrogenation of morphine to morphinone. The enzyme also exhibits significant activity for a variety of cyclic and alicyclic alcohols. In addition to xenobiotics, the enzyme catalyzes the dehydrogenation of 17-beta-hydroxysteroids with much higher affinities than morphine. Uses both NAD and NADP, but the activity is much greater with NAD than with NADP.
Catalytic activityi
Activity regulationi
Strongly inhibited by sulfhydryl reagents and ketamine, but not by pyrazole, barbital and indomethacine.
pH dependencei
Optimum pH is 9.3 with NAD as the cofactor.
