The structure of the bacterial signal transduction protein P(II) has been refined to an R factor of 13.2% using 3sigma data between 10 and 1.9 A.

Our earlier 2.7 A structure [Cheah, Carr, Suffolk, Vasudevan, Dixon & Ollis (1994). Structure, 2, 981-990] served as a starting model. P(II) is a trimeric molecule, each subunit has a mass of 12.4 kDa and contains 112 amino-acid residues. The refined model includes all 1065 protein atoms per subunit plus 312 water molecules. The high-resolution refinement confirms the correctness of our 2.7 A model, although it leads to a redefinition of the extent of various secondary-structural elements. The monomeric structure of P(II) exhibits an interlocking double betaalphabeta fold. This is a stable fold found in a number of proteins with diverse functions. The association of the protein into a trimer leads to a new structure which we describe in detail.

Publication Abstract from PubMedThe structure of the bacterial signal transduction protein P(II) has been refined to an R factor of 13.2% using 3sigma data between 10 and 1.9 A.
