Structure of the mammalian catalytic subunit of cAMP-dependent protein kinase and an inhibitor peptide displays an open conformation.
R.Karlsson, J.Zheng, N.Xuong, S.S.Taylor, J.M.Sowadski.
The crystal structure of a binary complex of the porcine heart catalytic (C) subunit of cAMP-dependent protein kinase (space group P4(1)32; a = 171.5 A) complexed with a di-iodinated peptide inhibitor, PKI(5-24), has been solved and refined to 2.9 A resolution with an overall R of 21.1%. The r.m.s. deviations from ideal bond lengths and angles are 0.022 A and 4.3 degrees. A single isotropic B of 17 A(2) was used for all atoms. The structure solution was carried out initially by molecular replacement of electron density followed by refinement against atomic coordinates from orthorhombic crystals of a binary complex of the mouse recombinant enzyme previously described [Knighton, Zheng, Ten Eyck, Ashford, Xuong, Taylor & Sowadski (1991). Science, 253, 407-414]. The most striking difference between the two crystal structures is a large displacement of the small lobe of the enzyme. In the cubic crystal, the beta-sheet of the small lobe is rotated by 15 degrees and translated by 1.9 A with respect to the orthorhombic crystal. Possible explanations for why this binary complex crystallized in an open conformation in contrast to a similar binary complex of the recombinant enzyme are discussed. This study demonstrates that considerable information about parts of a crystal structure can be obtained without a complete crystal structure analysis. Specifically, the six rigid-group parameters of a poly alanine model of the beta-structure were obtained satisfactorily from a crystal structure by refinement of difference Fourier coefficients based on an approximate partial structure model.

Figure 2.
ig. 2. Stereoview of the environ- ment of His87. The small lobe is indicated in red and the large lobe in blue. The inhibitor is indicated in black. (a) In the recombinant mouse C subunit, His87 of the small lobe interacts with the stble phosphoryation site of Thr197 of the large lobe and the carbonyl group of the main chain of Glu86 interacts with the side chain of Asng0. (b) In the pocine heart C subunit, His87 moves away from the phosphate of Thr197 and the side chain of Asng0 of the small lobe interacts with the carbonyl of Ala188 of the large lobe. istances are given in A.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
