Coupled residues
Many residues are in close spatial proximity in protein structures. This is true for most residues that are contiguous in the primary sequence, but also for many that are distal in sequence yet are brought into contact in the final folded structure. Because of this proximity, these residue's energy landscapes become coupled based on various biophysical phenomena such as hydrogen bonds, io… WebNov 15, 2024 · The evolutionarily coupled residues of PilT were consistent with its tertiary structure contacts, as well as the contacts that support the packing unit. There were also evolutionarily coupled ...

(a) CCMpred calculated coevolution matrices plotted as heat maps for the corresponding interaction schemes shown on the top of each panel. Each line corresponds to residues that are strongly (labelled as s, c = 10) or weakly (labelled as w, c = 4) coupled. WebMar 28, 2011 · Such clusters of coupled residues are particularly elusive in allosteric processes with a significant dynamically driven component (11–17), as in this case the allosteric signal propagation relies on subtle, …
WebApr 13, 2024 · Air gasification of biomass (sawdust) has been studied using an ASPEN plus model capable of predicting the producer gas composition and gasifier performance at different conditions. The methodology is based on an equilibrium-kinetic concept, which uses an equilibrium approach for combustion of tar and volatiles and a kinetic approach … Taking advantage of the celerity of ACI calculation, Ohm could yield the ACIs of all residue–residue pairs of even a large protein in a short period of time. Experimentally, inter-residue allosteric correlations can be determined using CHESCA based on the combination of agglomerative clustering and singular value … See more A perturbation propagation algorithm is the foundation for allosteric network analysis in Ohm; this algorithm predicts allosteric sites, pathways, critical residues, and inter-residue … See more The primary objective of the perturbation propagation algorithm is to identify candidate allosteric sites in proteins. We utilized a dataset compiled by Amor et al.22, which consists … See more As the perturbation propagation algorithm is de facto a random process, the results of each calculation differ. Hence, to evaluate the statistical significance of the perturbation … See more The perturbation propagation algorithm relies only on an input static structure, but protein structures are dynamic. Therefore we analyzed whether the conformational changes induced by in the CheY protein structure during the … See more
