very-long-chain 3-oxoacyl-CoA reductase;
very-long-chain 3-ketoacyl-CoA reductase;
very-long-chain beta-ketoacyl-CoA reductase;
KCR (gene name);
IFA38 (gene name)
Acting on the CH-OH group of donors;
With NAD+ or NADP+ as acceptor
BRITE hierarchy
(3R)-3-hydroxyacyl-CoA:NADP+ oxidoreductase
a very-long-chain (3R)-3-hydroxyacyl-CoA + NADP+ = a very-long-chain 3-oxoacyl-CoA + NADPH + H+ [RN:R10826]
(other) R07759
very-long-chain (3R)-3-hydroxyacyl-CoA [CPD:C20878];
NADP+ [CPD:C00006]
very-long-chain 3-oxoacyl-CoA [CPD:C20877];
NADPH [CPD:C00005];
H+ [CPD:C00080]
The second component of the elongase, a microsomal protein complex responsible for extending palmitoyl-CoA and stearoyl-CoA (and modified forms thereof) to very-long-chain acyl CoAs. The enzyme is active with substrates with chain length of C16 to C34, depending on the species. cf. EC, very-long-chain 3-oxoacyl-CoA synthase, EC, very-long-chain (3R)-3-hydroxyacyl-[acyl-carrier protein] dehydratase, and EC, very-long-chain enoyl-CoA reductase.
