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: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}.
