Project Title	Molecular Dynamics Simulation of Alanine Racemase in Pathogen Pseudomonas Aeruginosa for Drug Design Purposes
Summary	Pseudomonas aeruginosa is an opportunistic pathogen and associated with serious cross-infections in the hospitals and clinics; the D-alanine produced by alanine racemase (AlaR) is used for peptidoglycan biosynthesis in bacteria, so AlaR is a good drug design target on P. aeruginosa. Limited X-ray structure for the AlaR from P. aeruginosa (one available), so ten AlaR high-resolution structures from Geobacillus stearothermophilus would be studied and compared to Molecular Dynamics (MD) simulation trajectory of the AlaR from P. aeruginosa for drug design purposes.
Job Description	Students will learn how to set up the Alanine Racemase 3D structure in a water box based on the CHARMM force field, then do the MD simulation with UIUC/NAMD in a supercomputer in XSEDE resources. Students will learn how to resume job, collect, and transfer data to our Bioinformatics Lab where the MD trajectory data will be further processed and analyzed.
Computational Resources	We will need the supercomputing power in Stampede2 and/or Comet for the parallel supercomputing with UIUC/NAMD program. We might also use Comet GPU and/or Bridges GPU in XSEDE with the CUDA GPU version of UIUC/NAMD simulation program.

Training Plan	Planned trainings are shown as listed below. 1. Unix basics and common used Unix (Linux) commands in order to navigate the system in XSEDE and the Linux servers in Dr. Huang's Lab. 2. CHARMM force field basics 3. UIUC/NAMD set up and running basics 4. MD data collection and transfer basics 5. MD data analyses with UIUC/VMD program
Student Prerequisites/Conditions/Qualifications	The PI Dr. Hung-Chung Huang have been familiar with MD simulation work with a MD paper featured in the cover of Biopolymers Journal (March 2008 issue) as seen in the link below. https://onlinelibrary.wiley.com/doi/abs/10.1002/bip.20893
