    mechanisms In this report the photoionization of solution tyrosine and tyrosinate was investigated using transient picosecond absorption spectroscopy The results were compared to data acquired from a tyrosine containing β hairpin peptide This maquette peptide A is an 18 mer that exhibits π π interaction between tyrosine Y5 and histidine H14 Y5 and H14 carry out an orthogonal PCET reaction when Y5 is oxidized in the mid pH range Photolysis of all samples 280 nm instrument response 360 fs generated a solvated electron signal within 3 ps A signal from the S1 state and a 410 nm signal from the neutral tyrosyl radical were also formed in 3 ps Fits to S1 and tyrosyl radical decay profiles revealed biphasic kinetics with time constants of 10 50 and 400 1300 ps The PCET reaction at pH 9 was associated with a significant decrease in the rate of tyrosyl radical and S1 decay compared to electron transfer ET alone pH 11 This pH dependence was observed both in solution and peptide samples The pH 9 reaction may occur with a sequential electron transfer proton transfer ETPT mechanism Alternatively the pH 9 reaction may occur by coupled proton and electron transfer CPET CPET
