2pii Summary



The structure was published by Carr, P.D., Cheah, E., Suffolk, P.M., Vasudevan, S.G., Dixon, N.E., and Ollis, D.L., in 1996 in a paper entitled "X-ray structure of the signal transduction protein from Escherichia coli at 1.9 A." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 1995.

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

The PDB entry contains the structure of PII. This molecule has the UniProt identifier P0A9Z1 (GLNB_ECOLI)search. The sample contained 112 residues which is 100% of the natural sequence. Out of 112 residues 112 were observed and are deposited in the PDB.

The molecule most likely forms homotrimers.
