Structure of a protein tyrosine phosphatase

The structure was published by Lescop, E., Hu, Y., Xu, H., et al., Chen, J., Xia, B., and Jin, C., in 2006 in a paper entitled "The solution structure of Escherichia coli Wzb reveals a novel substrate recognition mechanism of prokaryotic low molecular weight protein-tyrosine phosphatases" (abstract).

The structure was determined using NMR spectroscopy and deposited in 2005.

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

The PDB entry contains the structure of Low molecular weight protein-tyrosine-phosphatase wzb. This molecule has the UniProt identifier P0AAB2 (WZB_ECOLI)search. The sample contained 167 residues which is 100% of the natural sequence. Out of 167 residues 147 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
