CC -!- FUNCTION: Component of the microsomal membrane bound fatty acid
CC elongation system, which produces the 26-carbon very long-chain fatty
CC acids (VLCFA) from palmitate. Catalyzes the reduction of the 3-
CC ketoacyl-CoA intermediate that is formed in each cycle of fatty acid
CC elongation. VLCFAs serve as precursors for ceramide and sphingolipids.
CC {ECO:0000255|HAMAP-Rule:MF_03107}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a very-long-chain (3R)-3-hydroxyacyl-CoA + NADP(+) = a very-
CC long-chain 3-oxoacyl-CoA + H(+) + NADPH; Xref=Rhea:RHEA:48680,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349,
CC ChEBI:CHEBI:85440, ChEBI:CHEBI:90725; EC=1.1.1.330;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03107};
CC -!- PATHWAY: Lipid metabolism; fatty acid biosynthesis.
CC {ECO:0000250|UniProtKB:P38286}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000255|HAMAP-Rule:MF_03107}; Single-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_03107}.
CC -!- SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR)
CC family. {ECO:0000255|HAMAP-Rule:MF_03107}.
