Studies of transfer RNA tertiary structure by singlet-singlet energy transfer.
This distance between a base next to the anticodon of tRNA and the 3' CpCpA terminus of the molecule has been estimated by singlet-singlet energy transfer experiments. The energy donor was the Y base of unknown structure found in yeast tRNA(phe). Three different energy acceptors were used: acriflavine, proflavinyl acetic acid hydrazide, and 9-hydrazino acridine. These were attached to the perio...
متن کاملA molecular model for singlet/singlet energy transfer of monovalent ligand/receptor interactions.
A stochastic model is described that predicts the degree of singlet/singlet energy transfer in complexes formed between monovalent ligands and monovalent receptors. The modeling approach is intended to serve as an analytical tool for approximating the level of fluorescence quenching that can be expected to occur in fluorescently labeled monovalent ligands and receptors that are bound together i...
متن کاملSinglet Oxygen and Electron-Transfer Mechanisms
The 9,lO-dicyanoanthracene-sensitized photooxidation of 2,3-diphenyl1,4-dioxene in CHICN produces ethylene glycol dibenzoate and small amounts of epoxide. Most of the diester is formed from singlet oxygen via the dioxetane, and only a small amount by electron transfer. The epoxide is a primary electron-transfer product. Various mechanistic possibilites for the electron-transfer process are cons...
متن کاملDouble-headed protease inhibitors from black-eyed peas. VI. Singlet-singlet energy transfer and other optical studies on the structure of trypsin and chymotrypsin complexes.
The geometry of the binary and ternary complexes of two black-eyed pea inhibitors with trypsin and chymotrypsin has been established by distance measurements using the technique of singlet-singlet energy transfer. Triangulation of measured distances in the ternary double-headed complex of the trypsin-chymotrypsin inhibitor (BEPCI) with trypsin and chymotrypsin limits the possible structural mod...
