BRITE hierarchy
Sysname
acetone:carbon-dioxide ligase (AMP-forming)
Reaction(IUBMB)
acetone + CO2 + ATP + 2 H2O = acetoacetate + AMP + 2 phosphate [RN:R05735]
Reaction(KEGG)
Substrate
acetone [CPD:C00207];
CO2 [CPD:C00011];
ATP [CPD:C00002];
H2O [CPD:C00001]
Product
acetoacetate [CPD:C00164];
AMP [CPD:C00020];
phosphate [CPD:C00009]
Comment
Requires Mg2+ and ATP. The enzyme from Xanthobacter sp. strain Py2 also carboxylates butan-2-one to 3-oxopentanoate.
