Gene Dr1184 from Deinococcus radiodurans codes for a Nudix enzyme, (DR-CoAse) that hydrolyzes the pyrophosphate moiety of coenzyme A (CoA)., Nudix enzymes with the same specificity have been found in yeast, humans, and mice. The three-dimensional structure of DR-CoAse, the first of a, Nudix hydrolase with this specificity, reveals that this enzyme contains, in addition to the fold observed in other Nudix enzymes, insertions that, are characteristic of a CoA-hydrolyzing Nudix subfamily. The structure of, the complex of the enzyme with Mg(2+), its activating cation, reveals the, position of the catalytic site. A helix, part of the N-terminal insertion, partially occludes the binding site and has to change its position to, permit substrate binding. Comparison of the structure of DR-CoAse to those, of other Nudix enzymes, together with the location in the structure of the, sequence characteristic of CoAses, suggests a mode of binding of the, substrate to the enzyme that is compatible with all available data.
