Monte Carlo Protein Folding: Simulations of Met-Enkephalin with Solvent-Accessible Area Parameterizations [PDF]

arXiv, 2004
Treating realistically the ambient water is one of the main difficulties in applying Monte Carlo methods to protein folding. The solvent-accessible area method, a popular method for treating water implicitly, is investigated by means of Metropolis simulations of the brain peptide Met-Enkephalin.

Genetic identification of the central nucleus and other components of the central extended amygdala in chicken during development

Frontiers in Neuroanatomy, 2014
In mammals, the central extended amygdala shows a highly complex organization, and is essential for animal survival due to its implication in fear responses.

Prediction of Peptide Conformation by Multicanonical Algorithm: A New Approach to the Multiple-Minima Problem [PDF]

J.Comput.Chem. 14 (1993) 1333-1338, 1993
We apply a recently developed method, multicanonical algorithm, to the problem of tertiary structure prediction of peptides and proteins. As a simple example to test the effectiveness of the algorithm, Met-enkephalin is studied and the ergodicity problem, or multiple-minima problem, is shown to be overcome by this algorithm.

Simultaneous mass spectrometry imaging of multiple neuropeptides in the brain and alterations induced by experimental parkinsonism and L-DOPA therapy

Neurobiology of Disease, 2020
Neuropeptides are important signalling molecules in the brain and alterations in their expression levels have been linked to neurological disorders such as Parkinson's disease. It is challenging to map neuropeptide changes across and within brain regions

Molecular dynamics, Langevin, and hybrid Monte Carlo simulations in multicanonical ensemble [PDF]

Chem. Phys. Lett. 259 (1996) 321 -330, 1997
We demonstrate that the multicanonical approach is not restricted to Monte Carlo simulations, but can also be applied to simulation techniques such as molecular dynamics, Langevin, and hybrid Monte Carlo algorithms. The effectiveness of the methods are tested with an energy function for the protein folding problem.

Variation of the Energy Landscape of a Small Peptide under a Change from the ECEPP/2 Force Field to ECEPP/3 [PDF]

J. Phys. Chem. B 101 (1997) 3304 -3310, 1997
The multicanonical ansatz is used to study variations in the energy landscape of a small peptide, Met-enkephalin, under a change from the ECEPP/2 force field to ECEPP/3. Local minima with energies up to 5 kcal/mol higher than the global minima are sampled and classified according to H-bridges and backbone angles.
