Project Title	Testing Supervised Molecular Dynamics for Curved Access Channels in p450
Summary	there are only a few hypotheses of how the drugs actually enter the enzyme in order to be metabolized. This question has implications for drug-drug interactions (effects when you need to take multiple medications) as well as drug design and discovery. This project will develop scripts to run Supervised Molecular Dynamics (SuMD) for the ingress of atorvastatin lactone (ARVL), and take preliminary data.
Job Description	The student will develop collective variables to try and "guide" ligand through various tunnels in p450 using NAMD. These will be evaluated for success by the student and adjust to work, and be optimized for each channel. The student will also run the simulations on the Bridges.
Computational Resources	Bridges regular memory 10000 SU.
Contribution to Community	Our work will continue to show the value in computational biophysics and how it can ask and answer scientific questions not yet possible experimentally. This will allow the community to continue showing that its roll in the Biology Century is pivotal and that clever techniques (such as SuMD) can leverage current hardware to obtain results at timescales not possible for another 5-10 years with standard techniques (conventional MD).
Position Type	Apprentice
Training Plan	The student will spend the first two weeks learning the basics of conventional MD (through the NAMD tutorial) and test runs on XSEDE. Then the student will learn about the collective variables module and how to implement it (NAMD tutorial on collective variables). The student will then create the collective variables for the straight channel (2e) and a bent one (2b) and test them out. The rest of the project will be iteratively learning to improve the collective variables by learning how to test their effectiveness and improve them.
Student Prerequisites/Conditions/Qualifications	Intermediate experience with any programming language and Linux.
