OLD YELLOW ENZYME (OYE1) DOUBLE MUTANT H191N:N194H

The structure was published by Brown, B.J., Deng, Z., Karplus, P.A., and Massey, V., in 1998 in a paper entitled "On the active site of Old Yellow Enzyme. Role of histidine 191 and asparagine 194." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.7 Å and deposited in 1998.

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

The PDB entry contains the structure of PROTEIN (NADPH DEHYDROGENASE 1). This molecule has the UniProt identifier Q02899 (OYE1_SACPS)search. The sample contained 399 residues which is 100% of the natural sequence. Out of 399 residues 399 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 is most likely monomeric.
