摘 要: | 正Dear editor,Light-driven Na~+ pumping rhodopsins(Na Rs),the next generation optogenetic tools,are a family of seven-helical transmembrane proteins and covalently link to a retinal chromophore~(1]).Na Rs have a putative Na~+ -conducting motif of Asn112-Asp116-Gln123~(1]),homologous to the H~+-conducting motif of Asp85-Thr89-Asp96 in H~+ pump bacteriorhodopsin(BR)~(2]).
