CAP: Conformation Angles Package - Displaying the Conformation Angles of Side Chains in Proteins

SUMMARY A graphics package has been developed to display all side chain conformation angles of the user selected residue in a given protein structure. The proposed package is incorporated with all the protein structures (solved using X-ray diffraction and NMR spectroscopy) available in the Protein Data Bank. The package displays the multiple conformations adopted by a single amino acid residue ...

CADB: Conformation Angles DataBase of proteins

Conformation Angles DataBase (CADB) provides an online resource to access data on conformation angles (both main-chain and side-chain) of protein structures in two data sets corresponding to 25% and 90% sequence identity between any two proteins, available in the Protein Data Bank. In addition, the database contains the necessary crystallographic parameters. The package has several flexible opt...

Conformation of amino acid side-chains in proteins.

We have analysed the side-chain dihedral angles in 2536 residues from I9 protein structures. The distributions of x1 and xz are compared with predictions made OII the basis of simple energy calculations. The x1 distribution is trimodal; the qposition of the side-chain (~rans to Ha), which is rare except in serine, the t position (trams to the amino group), and the g+ position (trans to the carb...

Some aspects concerning conformation of polypeptide chains in proteins.

The structure of (S)-N,N'-di-tert-butyl-2-[N-(1-phenylethyl)benzamido] malonamide contains two fragments of a polypeptide chain. This compound therefore can be taken as a model substance for details of protein conformation. In the crystalline state one peptide chain of the model molecule incorporates a hydrogen bond between two adjacent nitrogen atoms in the backbone. The acceptor for the hydro...

Boltzmann-type distribution of side-chain conformation in proteins.

We analyze packing imperfections in globular proteins as reflected in deviations of torsion angles from the equilibrium values for the isolated side chains. The distribution of conformations of methionine and lysine residues in a database of high-resolution structures is compared with energies of model compounds calculated with high-level quantum-mechanics. The distribution of the C-C and C-S t...
