The structure of crystalline and membrane-bound gramicidin A by vibrational analysis
(Elsevier, 1984-12-28)
The results of normal mode calculations on the [beta]4.4, [beta]6.3, [up arrow, down arrow][beta]5.6, and [up arrow, down arrow]][beta]7.2 structures of gramicidin A are compared with infrared and Raman spectra of crystalline ...
Reaction rate enhancement by surface diffusion of adsorbates
(Elsevier, 1992-06)
Ligands can be captured by a surface target through either direct bulk diffusion or surface diffusion following reversible adsorption to the surface. We have solved a steady state boundary value problem for a perfect sink ...
A polarized photobleaching study of chromatin reorientation in intact nuclei
(Elsevier, 1990-08-20)
Polarized fluorescence recovery after photobleaching (pFRAP) was used to monitor the effects that condensation, i.e. compaction and aggregation, have on the ([mu]s and ms) internal dynamics of chromatin in intact nuclei. ...
Mossbauer spectroscopy applied to the oxidized and semi-reduced states of the iron-molybdenum cofactor of nitrogenase
(Elsevier, 1989-07-31)
Mossbauer parameters at 125K for both the oxidized and semi-reduced states of FeMoco isolated from the MoFe protein of nitrogenase of [delta]/Fe=0.32 and 0.37 mm/s and [Delta]Eq=0.84 and 0.71 mm/s, respectively, are ...
Structure of normal and contracted tail sheaths of T4 bacteriophage
(Elsevier, 1967-07-28)
The structural arrangement of protein subunits in extended and contracted tail sheaths of T4 bacteriophage has been studied by optical diffractometry of electron micrographs. The analysis of such diffraction patterns shows ...
Lack of correspondence between the room-temperature phosphorescence decay-components and Trp residues in a series of Trp-->Cys or Trp-->Phemutants of human carbonic anhydrase II
(Elsevier, 1994-10-17)
The room temperature phosphorescence of native human carbonic anhydrase (CA), and several mutants of this enzyme has been investigated. In these mutants the seven tryptophan residues in the native protein have sequentially ...
Comments on "the interpretation of the EPR and Mossbauer spectra of two-iron, one-electron iron-sulfur proteins"
(Elsevier, 1971-12-03)
Evidence is presented indicating that the note mentioned in the title is incorrect in two important aspects. 1.) According to our results of ENDOR spectroscopy and computer simulations of Mossbauer spectra, the conclusions ...
