4.17. Comparison of the structures belonging to the hydratase/isomerase superfamily (IV)

The structure of the yeast Δ32-enoyl-CoA isomerase was compared by superposition studies with the other known structures within the hydratase/isomerase superfamily. For these comparisons, the following PDB entries were used: 2-enoyl-CoA hydratase-1 (liganded with acetoacetyl-CoA, 1DUB; liganded with octanoyl-CoA, 2DUB), 4-CBA–CoA dehalogenase (1NZY), methylmalonyl-CoA decarboxylase (unliganded, 1EF8; liganded, 1EF9) and Δ3,52,4-dienoyl-CoA isomerase (1DCI). All superpositions were done with the lsq option in O (Jones et al. 1991), using the Cα-atoms of 25 residues from β -strands as well as their equivalents in the other structures.
