Cyan fluorescent protein: Molecular dynamics, simulations, and electronic absorption spectrum

Article Abstract:

The dynamic and electronic absorption spectrum of enhanced cyan fluorescent protein (ECFT), a mutant of green fluorescent protein (GFP), was studied by means of a 1 ns molecular dynamics (MD) simulation. The result states that the two conformations are stable along 1 ns trajectories, the protein partly quenches the rotation of the chromophore around the two bridging bonds through repulsive van der Waals interactions and the spectra obtained for the two conformations of the protein are indistinct.

Interaction of the antitumoral drug pazelliptine with polynucleotides: a subpicosecond transient absorption study

Article Abstract:

A study was conducted to analyze the interaction of the antitumoral drug pazelliptine with polynucleotides. Subpicosecond time resolution on a large spectral range was carried out to perform tne analysis. A pump-probe system based on the Nd:YAG-pumped dye laser was then utilized to determine transient absorption measurements. Experimental results indicated that the transient absorption band between 400 and 600 nm was very sensitive to the type of pazelliptine-polynucleotide complex.

Molecular dynamics simulation of methylene blue-guanine complex in water: the role of solvent in stacking

Article Abstract:

Molecular dynamics simulation has been used to investigate the conformation of the methylene blue-guanine complex in water. It has been established that there are three factors involved in the methylene blue-guanine association in water.

Guanine, Methylene blue
