Crystal Structure of Human B-form Low Molecular Weight Phosphotyrosyl Phosphatase at 1.6 Angstrom Resolution

The structure was published by Zabell, A.P., Schroff, A.D., Bain, B.E., Van Etten, R.L., Wiest, O., and Stauffacher, C.V., in 2006 in a paper entitled "Crystal structure of the human B-form low molecular weight phosphotyrosyl phosphatase at 1.6-A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.63 Å and deposited in 2004.

The experimental data on which the structure is based was also deposited.

The PDB entry contains the structure of Low molecular weight phosphotyrosine protein phosphatase. This molecule has the UniProt identifier P24666 (PPAC_HUMAN)search. The sample contained 157 residues which is 99% of the natural sequence. Out of 157 residues 157 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.
