To examine the effect of the TM helix orientation on the interaction of the JM sequence with the membrane surface, we performed similar experiments as described above to determine whether PIP2 affected the fluorescence intensity of the Alexa probe incorporated at the C-terminus of the TM JM (WT) peptide.
S is a function of the equilibrium distribution of orientations of the interaction tensor in an internal reference frame: 3in which Y2 m are spherical harmonic functions and ⟨⟩ denotes an ensemble average over the probability distribution that the principal axis of the tensor is oriented with angles Ω =.
The linear programming model (1 - 10) infers the pathways given the source, the target and the whole network G V,E,D,C,T), where V is the set of proteins and DNAs, E is the set of protein-protein interactions and protein-DNA interactions, D defines the dissipation indix on each edge, C defines the capacity of each edge, and T defines the orientations of the interactions.
We have also incorporated one-headed myosin-V smooth muscle myosin rod chimeras (M5SH) into myosin rod filaments, allowing us to determine the orientation of the actomyosin interaction, finding that the stepsize of myosin-II depends on the angle between the cofilament and the actin filament [20].
To model the FAK-NT-p53 peptide interaction, the DOCK 6.0 software analyzed >10,000 possible orientations of this interaction, based on the scores of the resulting interfaces using electrostatics (ES) and van der Waals (vWS) energies.
In contrast, TrpAb delivers ammonia to the active site of TrpAa in a way that may impose particular demands upon the spatial orientation of the protein-protein interaction operating for the anthranilate synthase complex.
For both Binary and Linear models, there may be an orientation bias: the interaction of two factors may depend on the relative orientation of the two binding sites.
The ANN results suggest broad trends regarding peptide orientation and the interaction of charged residues as a function of their position in the peptide.
Moreover, our data strongly suggest that sRkB has the propensity to form K-turn structures, which are found to be functional RNA motifs involved in the assembly of ribonucleoprotein complexes and in the orientation of pseudoknot interactions in the aptamer structures of the SAM-I and lysine riboswitches [ 36, 37].
