Predicting the final folded structure of protein molecules and simulating their folding pathways is crucial importance for designing viral drugs studying diseases such as Alzheimer's at molecular level. To this end, letter investigates problem conformation prediction under constraint avoiding high-entropy-loss routes during folding. Using well-established kinetostatic compliance (KCM)-based non...

Actinidin was used to hydrolyse proteins in whey protein isolate (WPI) and milk concentrate (MPC) reduce immunoreactivity of β-lactoglobulin (β-LG) αs1-casein (αs1-CN). Samples were incubated at an enzyme substrate ratio 1:100 (5.21 units actinidin activity g−1 protein) 10 or 60 °C for up 31 5 h, respectively. Protein hydrolysis determined by the degree SDS-PAGE. Antigenicity hydrolysates β-LG ...

The cystic fibrosis transmembrane conductance regulator (CFTR) anion channel is essential to maintain fluid homeostasis in key organs. Functional impairment of CFTR due mutations the cftr gene leads fibrosis. Here, we show that first nucleotide-binding domain (NBD1) can spontaneously adopt an alternate conformation departs from canonical NBD fold previously observed. Crystallography reveals thi...

In this study, we examine the effects of binding to protein upon nucleotide conformation, by the comparison of X-ray crystal structures of free and protein-bound nucleotides. A dataset of structurally non-homologous protein-nucleotide complexes was derived from the Brookhaven Protein Data Bank by a novel protocol of dual sequential and structural alignments, and a dataset of native nucleotide s...
