In this paper, the fast spectral method [36], originally developed by Mouhot and Pareschi for the numerical approximation of the collision operator, is extended to deal with other collision kernels, such as those corresponding to the soft, Lennard Jones, and rigid attracting potentials.
The complex structure of active ERK2 (PDB ID: 2ERK) bound to Ets-1 (residues 29 138) (PDB ID: 2JV3) [21] was predicted using the molecular mechanics modeling approaches using a semi-rigid body potential smoothing energy minimization as described previously [13].
Then, the second phase analyses geometry by comparing topological structures and, subsequently, determines a potential rigid body transformation.
Sift CEO Jason Tan explained that in an earlier wave of e-commerce, companies relied on rules and rigid systems to flag potential fraudsters.
For given real rigid displacements, an instability potential was derived for the plate based on the rigid body rule.
Next, for given virtual rigid displacements, another instability potential was derived for the plate utilizing the equilibrium equations for the boundary tractions at the C1 and C2 states.
Interestingly, the latter rigid segment embraces a potential static curvature (centered at −98; see above) and is located near the 3′ end of the RUP_A element.
As expected, in the subset of binding sites in which no rotamer changes were observed, the Apo-bound and Holo forms show no significant differences in their steric potential for rigid binding sites.
By comparing the two instability potentials for the real and virtual rigid displacements, the total instability potential was recovered, which differs from the existing ones in the inclusion of the torsional terms.
This is especially true for non-rigid registration, where the potential for misregistering noise and artefacts becomes greater (see Additional file 1).
