Several isoforms of KAS with different substrate specificity are present in most species. We have determined the crystal structure of KAS II from Synechocystis sp. PCC 6803 to 1.54 A resolution giving a detailed description of the active site geometry. In order to analyze the structure-function relationships in this class of enzymes in more detail, we have compared all presently known three-dimensional structures of condensing enzymes from different pathways. The comparison reveals that these enzymes can be divided into three structural and functional classes. This classification can be related to variations in the catalytic mechanism and the set of residues in the catalytic site, e.g. due to differences in the nature of the second substrate providing the two-carbon elongation unit. The variation in the acyl-carrier (ACP or CoA) specificity might also be connected to this classification and residues involved in ACP binding in structure class 2 can be suggested based on the comparison. Finally, the two subunits in the dimer contribute differently to formation of the substrate binding-pocket in the three structural classes."xsd:string |
