摘要
For biomolecules of increased size and flexibility, more efficient and reliable strategies are always needed to determine their stable low-energy conformers. Here, we propose a fragment based step-by-step strategy to search for the full conformational space of biomolecules. In this strategy, the molecule is divided into several fragments and each of them is systematically optimized in a step-by-step fashion. It can significantly reduce the computational cost without losing any accuracy as demonstrated by the conformer search of several representative di-/tri-/tetra-peptides. Such an approach will be very useful for finding the stable conformers of large biomolecules.
