Mammalian soluble Guanylate Cyclase (sGC), working as a physiological NO receptor, is investigated using resonance Raman spectroscopy for NO bound states with different saturation levels in the presence and absence of effectors. The Fe–NO (νFe–NO) and N–O (νN-O) stretching bands appeared at 521 and 1681 cm-1, respectively, without effectors, but νN-O was split into 1681 and 1699 cm-1 in the presence of GTP and shifted to 1687 cm-1 in the presence of YC-1 or BAY 41-2272, while νFe-NO remained unaltered. The split two νN-O bands were independent of NO saturation levels. GTP or YC-1/BAY 41-2272 altered the vinyl and propionate bending modes from 423 to 399 cm-1 and 376 to 367 cm-1, respectively. Based on these observations, allosteric effects on NO …protein interactions are discussed.

ABSTRACTMetal-organic films were produced at ambient temperatures and pressures by the controlled hydrolysis of carboxylic acid and titanium isopropoxide mixtures. Pre-resonance Raman spectroscopy was used to study the effect of the organic acid chain length upon the nature of the resulting film. Propionic, butyric, valeric, hexanoic, and octanoic acids were studied, resulting in a proposed correlation between film quality and certain spectroscopic features of the alkoxide carboxylates. The choice of the carboxylic acid and the presence of an appropriate amount of water were shown to be critical in the development of a good film.
