Figure 7From: The crystal structures of the tri-functional Chloroflexus aurantiacus and bi-functional Rhodobacter sphaeroides malyl-CoA lyases and comparison with CitE-like superfamily enzymes and malate synthases Slabbed side view of the MCLC active site surface model in the closed conformation. A pocket at the protein surface accommodates the adenosine moiety of propionyl-CoA, whereas its pantetheine moiety is threaded into the tunnel-like active site cavity. The Mg2+ ion (green) is located at the very end of the tunnel and is coordinated by oxalate. Surface colored by atom type: red (oxygen), blue (nitrogen), yellow (sulfur).Back to article page
