TI  - Structure of a coenzyme A pyrophosphatase from Deinococcus radiodurans: a member 
      of the Nudix family.
PG  - 4110-8
AB  - 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.
