Crystal structure of Cordyceps militaris IDCase D323N mutant in complex with 5-carboxyl-uracil

2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid

Crystal structures of isoorotate decarboxylases reveal a novel catalytic mechanism of 5-carboxyl-uracil decarboxylation and shed light on the search for DNA decarboxylase.
