The phrase "a common conformation" is correct and usable in written English.
It can be used in contexts related to biology, chemistry, or structural analysis where you are discussing a frequently occurring shape or arrangement of molecules or structures.
Example: "In protein chemistry, a common conformation of the alpha-helix is crucial for its function."
Alternatives: "a typical structure" or "a standard arrangement".
Molecular dynamics simulations showed that the binding pocket in the three MDM4 structures converged to a common conformation after removal of the ligands, indicating that the differences are due to induced fit.
The two simulations did not converge to a common conformation; moreover, the final complex of A2 resulted in a partially unfolded structure.
These repeats, which contain three alpha-helices, adopt a common conformation named helix-turn-helix motives.
Ten years ago a common conformation was demonstrated among soluble oligomeric species from amyloid proteins/peptides of diverse sequence and structures that cross react with the A11 antibody (Kayed et al., 2003).
Although pacifastin-related peptides share a common conformation, the family can be divided into at least two separate groups (I & II) based on different intramolecular interactions in the inner core region [ 22].
This apparent anomaly could be explained [ 56, 57, 45] by it being so toxic as an amyloid precursor that natural selection has eliminated most proteins that form α-sheet. Overall, whether or not α-sheet does prove to be the main precursor to amyloid, it seems likely it was a common conformation of the earliest peptides.
On visual inspection, no clear interpretation of the projected axes emerged but the points of meeting for trajectory 2 and 3 showed a series of two-helix conformandons and a common flipped conformation (marked on Fig. 9).
Previous studies suggest that the toxic soluble-oligomeric form of different amyloid proteins share a common backbone conformation, but the amorphous nature of this oligomer prevents its structural characterization by experiment.
Analysis of the conformation of this disaccharide in multiple crystal structures reveals that in many cases it assumes a common preferred conformation in which the N-acetyl group of GlcNAc is positioned above the mannose residue, making van der Waals interactions with the B face of the hexose (Petrescu et al. 1999).
Crystallographic study indicates that a set of known PREP inhibitors inhabit a common binding conformation, and this H-bond network is not significantly altered.
In the crystal structures of compounds 2 6 the piperazine ring was in a common chair conformation (with the two N-substituents in equatorial positions) as indicated by deviations of nitrogen atoms in opposite directions from the plane defined by the ring carbons.
