Functionalization of a protein surface with per-O-methylated β-cyclodextrin.
Per-O-methylated β-cyclodextrin (CD) bearing an iodoacetamide group at the 6-position was synthesized to functionalize protein surfaces. Bovine serum albumin (BSA) was quantitatively modified with the CD derivative by the S(N) 2 reaction of iodoacetamide with a cysteine residue (Cys34) on the BSA surface. The resultant CD-functionalized BSA (BSA-CD) spontaneously dimerized upon addition of an anionic tetraarylporphyrin (TPPS) through the supramolecular 1:2 complexation between TPPS and CD on the protein surface. The BSA-CD/TPPS complex further complexed with ferric protoporphyrin IX (hemin) in the hydrophobic pockets of albumin to form a hemin/BSA-CD/TPPS ternary complex in which static fluorescence quenching occurred owing to intramolecular electron transfer from the photoexcited TPPS to hemin.
