Chain A,B (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.
