As good as it gets? Folding molecular dynamics simulations of the LytA choline-binding peptide result to an exceptionally accurate model of the peptide structure

Folding simulations of a choline-binding peptide derived from the Streptococcus pneumoniae LytA protein converged to a model of the peptide's folded state structure which is in outstanding agreement with the experimentally-determined structures, reaching values for the root mean squared deviation as low as 0.24 Å for the peptide's backbone atoms and 0.65 Å for all non-hydrogen atoms.
