Chain A   (TRN2_DATST | P50163)
molecular function
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
    GO:0050358    tropinone reductase activity    Catalysis of the reaction: NADP(+) + pseudotropine = H(+) + NADPH + tropinone.
biological process
    GO:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
    GO:0009710    tropane alkaloid biosynthetic process    The chemical reactions and pathways resulting in the breakdown of tropane alkaloids, compounds containing the 8-methyl-8-azabicyclo(3.2.1)octane ring system.
