CRYSTAL STRUCTURE OF INOSITOL POLYPHOSPHATE 1-PHOSPHATASE AT 2.3 ANGSTROMS RESOLUTION

The structure was published by York, J.D., Ponder, J.W., Chen, Z.W., Mathews, F.S., and Majerus, P.W., in 1994 in a paper entitled "Crystal structure of inositol polyphosphate 1-phosphatase at 2.3-A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 1994.

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

The PDB entry contains the structure of INOSITOL POLYPHOSPHATE 1-PHOSPHATASE. This molecule has the UniProt identifier P21327 (INPP_BOVIN)search. The sample contained 400 residues which is 100% of the natural sequence. Out of 400 residues 400 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.
