Fig. 1From: Genetically encoded phosphatidylserine biosensor for in vitro, ex vivo and in vivo labellingStructural models of recombinant C2 fusion proteins. a C2-mKate aligned to experimentally defined structures of C2 domain (PDB ID: 2L9L) and mKate (PDB ID: 3BXC). b C2-SNAP aligned to experimentally defined structures of C2 domain and SNAP-tag (PDB ID: 3KZZ). Purple dashed circle marks putative site of C2 and PS interaction, including critical amino acids K24 and K45 in redBack to article page
