molecular function
    GO:0004318    enoyl-[acyl-carrier-protein] reductase (NADH) activity    Catalysis of the reaction: acyl-[acyl-carrier protein] + NAD+ = trans-2,3-dehydroacyl-[acyl-carrier protein] + NADH + H+.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
biological process
    GO:0006633    fatty acid biosynthetic process    The chemical reactions and pathways resulting in the formation of a fatty acid, any of the aliphatic monocarboxylic acids that can be liberated by hydrolysis from naturally occurring fats and oils. Fatty acids are predominantly straight-chain acids of 4 to 24 carbon atoms, which may be saturated or unsaturated; branched fatty acids and hydroxy fatty acids also occur, and very long chain acids of over 30 carbons are found in waxes.
    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.
