Abstract
A human dihydropteridine reductase (EC 1.6.99.10) has been created fro m a rat cDNA clone by a single five-oligonucleotide mutagenesis reacti on and expressed in good yield in Escherichia coli. The enzyme has bee n purified to homogeneity, and kinetic identity to the naturally occur ring enzyme has been proven. Crystallization has also been achieved, a nd the crystal structure was solved using 2.5 angstrom data that was r efined to an R value of 16.9%. The structure described in this report represents the first complete structural characterization of this impo rtant human enzyme.
