Pyrrolinecarboxylysine (Pcl) is readily incorporated into proteins expressed in Escherichia coli and in mammalian cells by the unmodified pyrrolysyl-tRNA/tRNA synthetase pair in response to the amber nonsense (TAG) codon. Pcl is specifically and covalently modified by 2-aminoacetophenone (2-AAP) or 2-aminobenzaldehyde (2-ABA) groups. Taking advantage of the reversibility of this reaction, the authors illustrate that Pcl-containing proteins can be purified by a resin bearing the immobilized 2-AAP moiety. Moreover, the authors demonstrate that 2-ABA reagents can be used to simultaneously elute and site-specifically modify two model proteins with fluorophores, a biotin affinity label, a disaccharide and a nitrophenyl hapten. These data suggest that Pcl can in principle be used as a single amino acid affinity purification and modification tag.
