WebHowever, alteration to aspartate, glutamate, and glutamine blocked passage of water, glycerol, and other organic solutes. While LmAQP1 is a mercurial insensitive water channel, mutation of the adjacent threonine (Thr164) to cysteine led to inhibition of water passage by Hg 2+. This inhibition could be reversed upon addition of β-mercaptoethanol. WebApr 1, 2024 · In silico alanine scanning mutagenesis was investigated by conducting molecular dynamics simulations on the wild-type of both proximal and distal Cys-His boxes of the human immunodeficiency virus type 1 Nucleocapsid protein p7 and on their mutated structures to get insight into the impact of mutation on the structural behavior of …

Alanine Scanning was used to determine simultaneously the functional contributions of 19 side chains buried at the interface between human growth hormone and the extracellular domain of its receptor. Each amino acid in the side chains was substituted by alanine. Then shotgun scanning method which combines the concepts of alanine scanning mutagenesis and binomial mutagenesis with phage display technology was used. WebOct 12, 2015 · We report here that a commonly studied DUB mutation, in which the catalytic cysteine is replaced with alanine, can dramatically increase the affinity of some DUBs for ubiquitin. Overexpression of these tight-binding mutants thus has the potential to sequester cellular pools of monoubiquitin and ubiquitin chains. cryptographic key vs certificate
