P1 NUCLEASE IN COMPLEX WITH A SUBSTRATE ANALOG

The structure was published by Romier, C., Dominguez, R., Lahm, A., Dahl, O., and Suck, D., in 1998 in a paper entitled "Recognition of single-stranded DNA by nuclease P1: high resolution crystal structures of complexes with substrate analogs." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 1997.

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

The PDB entry contains the structure of P1 NUCLEASE. This molecule has the UniProt identifier P24289 (NUP1_PENCI)search. The sample contained 270 residues which is 100% of the natural sequence. Out of 270 residues 264 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.
