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.
