General Information

General Information	Comment	Organism
physiological function	enzyme is part of an autotrophic 3-hydroxypropionate/4-hydroxybutyrate carbon dioxide assimilation pathway in Metallospaera sedula. In the pathway, CO2 is fixed with acetyl-CoA/propionyl-CoA carboxylase as key carboxylating enzyme. One acetyl-CoA and two bicarbonate molecules are reductively converted via 3-hydroxypropionate to succinyl-CoA	Metallosphaera sedula
