The implication is that a rigid orientation of a peptide in chromatography confers sensitivity to its sequence as well as to the total content of charged residues.
Using the ensemble optimization method (EOM) program 37, we find that TPR2A and TPR2B are no longer fixed in a rigid orientation in the Hop Y354E mutant but are adopting a predominantly dynamic conformation in which the two domains are disconnected (Fig 4C).
This is consistent with the data in Figure 5 that indicated that an extra basic residue anywhere in the sequence may represent an alternative to the N-terminus as a stationary phase binding site in SCX, eliminating the rigid orientation of peptide binding observed for peptides containing just a single basic residue.
A rigid spinning object, for example, continues to spin at a constant rate and with a fixed orientation unless influenced by the application of an external torque.
The inner simulations consist of: (1) Optimization of the rigid-body orientation: The peptide rigid-body orientation is optimized by a Monte-Carlo simulation consisting of 50 random rigid-body transformations (translational magnitude of 1 Å and rotational magnitude of 10° on average in each step).
Nervously pursuing her first foray into a same-sex relationship, Kissing Jessica Stein sagely observes female sexuality in a wider context than rigid sexual orientation.
tie points, lines, perspective centers derived from direct georeferencing (i.e. GNSS), ground control points (GCP), the lever-arm vector separating the GNSS antenna and the perspective center, rigid relative orientation between cameras.
A range of different observations equations, constraints and unknowns (i.e. parameters) are allowed in the adjustment routine, among them: tie points, lines, perspective centers derived from direct georeferencing (i.e. GNSS), ground control points (GCP), the lever-arm vector separating the GNSS antenna and the perspective center, rigid relative orientation between cameras.
In short, the peptide backbone conformation is perturbed over 50 random Monte-Carlo moves while the peptide rigid body orientation remains fixed.
Since the unregistered images may contain considerable global and local nonlinear deformations in addition to global rigid deformation, orientation detection between images has to be robust to considerable complex deformation, partial occlusion, and illumination changes.
We next carried out simultaneous quasi-Newton optimization of the compound rigid body orientation and the sidechain torsion angles, and in some cases, the torsion angles of the compound and the backbone torsion angles in the binding site, using the complete Rosetta energy function.
