Tyrosine 111-119 ribonuclease A family member 1, pancreatic Homo sapiens 41-55 17384067-1 2007 The six tyrosine residues of ribonuclease A (RNase A) are used as individual intrinsic probes for tracking local conformational changes during unfolding. Tyrosine 8-16 ribonuclease A family member 1, pancreatic Homo sapiens 29-43 17384067-1 2007 The six tyrosine residues of ribonuclease A (RNase A) are used as individual intrinsic probes for tracking local conformational changes during unfolding. Tyrosine 8-16 ribonuclease A family member 1, pancreatic Homo sapiens 45-52 17384067-2 2007 The fluorescence decays of RNase A are well described by sums of three exponentials with decay times (tau(1) = 1.7 ns, tau(2) = 180 ps, and tau(3) = 30 ps) and preexponential coefficients (A(1) = 1, A(2) = 1, and A(3) = 4) at pH 7, 25 degrees C. The decay times are controlled by photo-induced electron transfer from individual tyrosine residues to the nearest disulphide (-SS-), bridge, which is distance (R) dependent.
