molecular function
    GO:0008677    2-dehydropantoate 2-reductase activity    Catalysis of the reaction: (R)-pantoate + NADP(+) = 2-dehydropantoate + H(+) + NADPH.
    GO:0050661    NADP binding    Interacting selectively and non-covalently with nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions; binding may be to either the oxidized form, NADP+, or the reduced form, NADPH.
    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.
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:0015940    pantothenate biosynthetic process    The chemical reactions and pathways resulting in the formation of pantothenate, the anion of pantothenic acid. It is a B complex vitamin that is a constituent of coenzyme A and is distributed ubiquitously in foods.
    GO:0033317    pantothenate biosynthetic process from valine    The chemical reactions and pathways resulting in the formation of pantothenate, the anion of pantothenic acid, from other compounds, including valine.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
