Madeline4 months ago 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.
