Our joint project with Drs. Zolkiewski and Prakash has been funded by NIGMS through a 5-year competitive R01 grant! The project aims to develop multi-scale enhanced sampling techniques for IDPs and to combine simulation with experiment to determine how the structure and interactions of p53 transactivation domain may be affected by post-translational modifications and cancer-associated mutations.

Congratulations to Xiaorong and Alex for having their first papers from K-State accepted by Biophysical Journal. Their work combine structural analysis and atomisitc simulation to demonstrate that the BH3-only protein binding interface of anti-apoptotic protein Bcl-xL is highly dynamic and poised to adopt alternative conformations in response to ligand binding.

Warm congratulations to Weihong for getting his paper on a very nice multi-scale enhanced sampling (MSES) method accepted by JCTC as a Letter. The method addresses one of the key limitations in the popular temperature replica exchange (T-RE) sampling technique for simulating large-scale conformational transitions such as protein folding. The basic idea is to couple efficient topology-based coarse-grained models with all-atom ones to enhance the sampling of atomistic protein energy landscape. The bias from the coupling is removed by Hamiltonian replica exchange, thus allowing one to benefit simultaneously from faster transitions of coarse-grained modeling and accuracy of atomistic force fields.

(all replicas in MSES sample similar and complete conformational space, while replicas in traditional T-RE are trapped in various major states)
