To further verify binding interaction from the peptide isolates, scanning electron microscopy (SEM) was used to directly visualize DBAD1 binding to bulk aluminum (a representative figure shown in the Figure 2B inset).
Transcription factor-DNA binding interactions from six additional studies were added, including TGA2 (Thibaud-Nissen et al., 2006), AP1 (Kaufmann et al., 2010), BES1 (Yu et al., 2011), BZR1 (Sun et al., 2010), FLC (Deng et al., 2011) in addition to our data.
Lists of literature curated binding sites with Pub-med references and a spreadsheet of binding interactions parsed from the above databases can be downloaded in Additional File 2. Motif Discovery was performed on WT1 known targets and new predictions.
Epistasis arises both from the nature of the binding interaction and from the resulting fitnesses.
We then extracted the binding (protein protein) interactions from the Composite SPLN to build a Binding SPLN for RLS analysis (Table S3).
The kinetic parameters of the binding interactions were calculated from the sensorgrams by nonlinear curve fitting using BIAEVALUATION software (BIAcore).
Provided that contributions from chemical and conformational exchange resulting from direct binding interactions are removed, the degree of line-broadening reflects the tumbling rate (i.e the size and shape) of the complex.
While crystal structures of NW bound to GluA2 LBD differ little when the pH of the crystallization medium is changed from 6.5 to 3.5, the ITC results suggest that the binding interactions in the charged form differ significantly from those in the uncharged form.
This incomplete stimulation of ATPase activity likely results from relatively weaker binding interactions between the NBD and linker peptide in the trans configuration (HscA386 and peptide) as compared to the cis (HscA395) configuration.
It should be noted that fish also appear to choose mating partners based on MHC haplotype, presumably via an olfactory-mediated process [ 53]; the OlfC receptors may therefore mediate chemoreception of peptide cues via such allosteric interactions, distinct from "orthosteric" ligand binding interactions within the conventional clamshell binding pocket.
