KEGG   ENZYME: 1.3.1.84Help
Entry
EC 1.3.1.84                 Enzyme                                 

Name
acrylyl-CoA reductase (NADPH)
Class
Oxidoreductases;
Acting on the CH-CH group of donors;
With NAD+ or NADP+ as acceptor
BRITE hierarchy
Sysname
propanoyl-CoA:NADP+ oxidoreductase
Reaction(IUBMB)
propanoyl-CoA + NADP+ = acryloyl-CoA + NADPH + H+ [RN:R00919]
Reaction(KEGG)
Substrate
propanoyl-CoA [CPD:C00100];
NADP+ [CPD:C00006]
Product
acryloyl-CoA [CPD:C00894];
NADPH [CPD:C00005];
H+ [CPD:C00080]
Comment
Catalyses a step in the 3-hydroxypropanoate/4-hydroxybutanoate cycle, an autotrophic CO2 fixation pathway found in some thermoacidophilic archaea [1]. The enzyme from Sulfolobus tokodaii does not act on either NADH or crotonyl-CoA [2]. Different from EC 1.3.1.8, which acts only on enoyl-CoA derivatives of carbon chain length 4 to 16. Contains Zn2+.
