PDB entry 2pl1 (supersedes 2eub)

Berrylium Fluoride activated receiver domain of E.coli PhoP

The structure was published by Bachhawat, P. and Stock, A.M., in 2007 in a paper entitled "Crystal Structures of the Receiver Domain of the Response Regulator PhoP from Escherichia coli in the Absence and Presence of the Phosphoryl Analog Beryllofluoride." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2007.

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

The PDB entry contains the structure of Transcriptional regulatory protein phoP. This molecule has the UniProt identifier P23836 (PHOP_ECOLI)search. The sample contained 121 residues which is < 90% of the natural sequence. Out of 121 residues 120 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 most likely forms homodimers.
