Like at AMYRs, these features require the expansion of extracellular TM bundle of CTR through outward movements of TM1, ECL1/TM3, TM4/ECL2 and a small shift in the positioning of the mid-region of the peptide at the start of the N-terminal helix, relative to rAmy when bound to the CTR in the bypass conformation (Fig
Overall, there is not sufficient evidence to recommend B12 on its own for the elderly with impaired cognitive function, although those with early symptoms may benefit
