Extended Data Fig. 1 Overview of anti-GFP nanobody compatible fluorescent protein variants.

( a ) Crystal structure of GFP bound to anti-GFP nanobody (Nb) (PDB ID: 3K1K ) 43 with GFP shown in green with cartoon rendering, anti-GFP Nb shown in blue with surface rendering, and specific residues on GFP that make contact with the anti-GFP Nb shown in stick rendering. ( b ) Front-view of the anti-GFP nanobody binding surface of GFP with participating residues shown in stick rendering. Residues mutated in other fluorescent protein variants colored in salmon. ( c ) Multiple sequence alignment of various fluorescent protein variants. Columns corresponding to residues contacted by the anti-GFP Nb are highlighted in yellow, and any mutations to these positions are highlighted in red. Mutation of I146N was previously shown to restore anti-GFP Nb binding in CFP variants 53 .
