1dhr Summary



The structure was published by Varughese, K.I., Skinner, M.M., Whiteley, J.M., Matthews, D.A., and Xuong, N.H., in 1992 in a paper entitled "Crystal structure of rat liver dihydropteridine reductase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 1992.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of DIHYDROPTERIDINE REDUCTASE. This molecule has the UniProt identifier P11348 (DHPR_RAT)search. The sample contained 241 residues which is 100% of the natural sequence. Out of 241 residues 236 were observed and are deposited in the PDB.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms homodimers.
