Protein surface recognition by porphyrin-based receptors

Research output: Contribution to journalShort surveypeer-review


Protein surface recognition is largely unexplored owing to the large solvent exposed surface and lack of proper molecular scaffolds to match the binding residues. This review describes the design, synthesis, and fluorescence binding studies of functionalized porphyrins aimed at targeting surface residues of proteins through complementary recognition. The pattern of lysine residues surrounding the heme-edge of horse heart cytochrome c has been targeted by tetraphenylporphyrin and tetrabiphenylporphyrin receptors that bind with nano- and sub-nanomolar affinity. Other designed porphyrin-based receptors also recognize potassium channel as a target. The strategies for protein surface recognition offer a new use for porphyrins as molecular scaffolds.
