Protein components of the U6 snRNP (Prp24p and LSm2-8) are thought to act cooperatively in facilitating the annealing of U6 and U4 snRNAs during U4/U6 di-snRNP formation. To learn more about the spatial arrangement of these proteins in S. cerevisiae U6 snRNPs, we investigated the structure of this particle by electron microscopy. U6 snRNPs, purified by affinity chromatography and gradient centr...
The two cluster anions, PtMgH3(-) and PtMgH5(-), were studied by photoelectron spectroscopy and theoretical calculations. Experimentally-determined electron affinity (EA) and vertical detachment energy (VDE) values were compared with those predicted by our computations; excellent agreement was found. The calculated structures of PtMgH3(-) and PtMgH3 both exhibit η2-bonded H2 moieties. Activatio...
The photoelectron spectrum of the anilinide ion has been measured. The spectrum exhibits a vibrational progression of the CCC in-plane bending mode of the anilino radical in its electronic ground state. The observed fundamental frequency is 524 ± 10 cm(-1). The electron affinity (EA) of the radical is determined to be 1.607 ± 0.004 eV. The EA value is combined with the N-H bond dissociation ene...
