Effect of short- and long-range interactions on trp rotamer populations determined by site-directed tryptophan fluorescence of tear lipocalin.

Autor: Oktay K Gasymov, Adil R Abduragimov, Ben J Glasgow

Publikováno v: PLoS ONE, Vol 8, Iss 10, p e78754 (2013)

In the lipocalin family, the conserved interaction between the main α-helix and the β-strand H is an ideal model to study protein side chain dynamics. Site-directed tryptophan fluorescence (SDTF) has successfully elucidated tryptophan rotamers at p

Exploring protein solution structure: Second moments of fluorescent spectra report heterogeneity of tryptophan rotamers

Autor: Oktay K. Gasymov, Adil R. Abduragimov, Ben J. Glasgow

Publikováno v: Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy. 150:909-920

Trp fluorescent spectra appear as a log-normal function but are usually analyzed with λmax, full width at half maximum, and the first moment of incomplete spectra. Log-normal analyses have successfully separated fluorescence contributions from some

Publikováno v: The Journal of Physical Chemistry. B

Trp is the most spectroscopically informative aromatic amino acid of proteins. However, the near-UV circular dichroism (CD) spectrum of Trp is complicated because the intensity and sign of (1)La and (1)Lb bands vary independently. To resolve vibronic
