Direct Imaging of Water/Lipid Interface by Frequency Modulation Atomic Force Microscopy at Sub-Angstrom Resolution

Frequency modulation atomic force microscopy (FM-AFM) has been used in ultra high vacuum (UHV) environments for investigating subnanometer-scale structures and functions of various surfaces. Until recently, however, its operating environment had been limited only to UHV, which has prevented its practical applications in air and liquids. Recently, Fukuma et al. presented a way to overcome this l...

Structure of a yeast spliceosome at 3.6-angstrom resolution.

Splicing of precursor messenger RNA (pre-mRNA) in yeast is executed by the spliceosome, which consists of five small nuclear ribonucleoproteins (snRNPs), NTC (nineteen complex), NTC-related proteins (NTR), and a number of associated enzymes and cofactors. Here, we report the three-dimensional structure of a Schizosaccharomyces pombe spliceosome at 3.6-angstrom resolution, revealed by means of s...

Interfacial atomic structure analysis at sub-angstrom resolution using aberration-corrected STEM

The atomic structure of a SiGe/Si epitaxial interface grown via molecular beam epitaxy on a single crystal silicon substrate was investigated using an aberration-corrected scanning transmittance electron microscope equipped with a high-angle annular dark-field detector and an energy-dispersive spectrometer. The accuracy required for compensation of the various residual aberration coefficients t...

Contrast transfer and resolution limits for sub-angstrom high-resolution transmission electron microscopy.

The optimum imaging of an object structure at the sub-angstrom length scale requires precise adjustment of the lens aberrations of a high-resolution instrument up to the fifth order. A least-squares optimization of defocus aberration C1, third-order spherical aberration C3, and fifth-order spherical aberration C5 yields two sets of aberration coefficients for strong phase contrast up to the inf...

Proton transfer pathways in bacteriorhodopsin at 2.3 angstrom resolution.

Photoisomerization of the retinal of bacteriorhodopsin initiates a cyclic reaction in which a proton is translocated across the membrane. Studies of this protein promise a better understanding of how ion pumps function. Together with a large amount of spectroscopic and mutational data, the atomic structure of bacteriorhodopsin, determined in the last decade at increasing resolutions, has sugges...
