WebMethane (CH4) is a molecule that is a perfect tetrahedron, and so it is commonly said that no isomerism is possible with methane. However, the carbon-hydrogen bonds of methane constantly vibrate and bend, so that on very short timescales an apparent isomerism can be said to exist. But these structures are not energy minima, and so they do not qualify as … WebIn contrast, high-resolution cryo-EM studies of MsbA reconstituted in nanodiscs or peptidiscs showed a much closer distance between the NBDs under apo conditions (IF narrow conformation) (9, 18).In light of other ABC exporter apo structures exhibiting close inter-NBD distances (19–21), these more recently determined MsbA structures led to the …
