Job title: 
PhD Student position in the field of computational chemistry and biophysics at the Research Centre for Natural Sciences
Contract type: 
fixed term
Location: 
Institute of Materials and Environmental Chemistry, Research Centre For Natural Sciences, H-1117 Magyar tudósok körútja 2., Budapest, Hungary
Position starts: 

Immediate start is possible, or as agreed with the successful applicant.

Salary: 
Due to the Momentum program the position offers and increased salary compared to the official PhD stipends currently issued in Hungary.
Description: 

The Biomolecular self-assembly “Momentum” research group is looking for a PhD student to conduct research in the field of theoretical biophysics.

 

The successful candidate will carry out primarily theoretical simulations employing molecular dynamics (MD) and quantum chemistry (QM, QM/MM) techniques to reveal mechanistic aspects in members of the RecA-like helicase family. The main focus will be on elucidating interactions between the micro- and macroscale within DNA-Protein complexes. The candidate will take an active part in designing and performing models and simulations, in data analysis and in writing scientific papers.

Scientific background: 

In a wide range of biological activities, from cell locomotion to membrane transport, Nature deploys numerous sophisticated molecular machines which have become highly optimized for performance and controllability. Rational design and engineering of similarly complex biosystems is a very exciting field with a potential to dramatically alter future’s medicine or industrial biochemistry. However, to overcome major challenges in design of artificial enzymes, the precise understanding of control mechanism on key reaction steps by larger molecular scale structure and dynamics is required. FoF1 ATP synthase is interesting as a model system: a delicate molecular machine synthesizing or hydrolyzing ATP utilizing a rotary motor. (1-2) ATP synthase is a member of the RecA-like helicase family, and it is particularly interesting how the structural and residual differences of the same family determine the ATP hydrolysis mechanism and its effect on the overall function of these enzymes. Rad51, RadA and RecA are examples from this group of proteins, which fulfill particularly important roles in cellular functions: the repair of damaged DNA and the maintenance of genomic diversity. Despite the numerous studies, many details are still uncovered, especially the role of ATP hydrolysis and the description of the reaction mechanism at the atomic level. Computational biophysics provides an adequate set of tools to describe the atomic level structural differences and accurate energetics of the system. By using my experience in different quantum mechanical (QM/MM) and molecular dynamics simulations (MD), we would like to expand our current understanding of RecA enzymes, aiming to provide details on the coupling of reaction steps with the large scale motions.
