Example sentences for: torsion

How can you use “torsion” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Axial rotation was tested by mounting the specimens in the centre of the material-testing machine, so that the axis of torsion lies midway between the centre and the posterior edge of the vertebral body in the sagittal plane.

  • Residues that differed in side chain type were constructed using a minimum perturbation (MP) technique [ 24 ] . The MP method changes a given amino acid to the target amino acid preserving the values of equivalent torsion angles between the two side chains, where available.

  • We initially start with an all-atom conformation where the torsion values for residues predicted to be in helix/sheet by PSIPRED secondary structure prediction [ 38 ] are set to idealised values [ 33 ] . The remaining φ/ψ values are set in an extended conformation.

  • Energy terms included Van der Waals, electrostatic, hydrogen bond, and torsion terms [ 10 ] .

  • Side chain conformations are predicted by simply using the most frequently observed rotamer in a database of protein structures [ 30 ] . New conformations are generated by perturbing the existing conformation at an arbitrary residue by one of two methods: ( i ) the torsion values for three residues with identical sequence from a known structure are used to modify the current conformation, similar in spirit to that of Baker and colleagues [ 39 ] ; ( ii ) one of possible 14 torsion (φ/ψ) values derived based on the most frequently occurring torsion values for a given residue in a database of known structures.
