Molecular simulation of ArsD, an arsenic metallochaperone with Assisted Model Building with Energy Refinement

2013-01-01 Aylin Sahin

IAESTE IndiaMIT – 2013. Both prokaryotes and eukaryotes have arsenic detoxifying systems, frequently involving extrusion from cytosol. The 120 residue ArsD is encoded by the arsRDABC operon of plasmid R773 that confers resistance to arsenite and antimonite in Escherichia coli. A molecular dynamics study was carried out to construct the missing parts of the ArsD structure. The final model will be used to examine the structure of ArsD and its interaction with the partner protein, ArsA.

Molecular simulation of ArsD, an arsenic metallochaperone with AMBER

2012-01-01 Ariana Karakutuk

IAESTE IndiaMIT – 2012. Arsenic, a toxic metalloid, causes a variety of health problems. The ArsD metallochaperone delivers trivalent metalloids, As(III) or Sb(III), to the ArsA ATPase, the catalytic subunit of the ArsAB As(III) efflux pump. In this study, we have carried out the molecular dynamics simulation experiments using AMBER program to understand the open form of ArsA as well as arsenic binding site of ArsD.

The crystallisation trials using optical forces

2012-01-01 Mahendra K

X-ray crystallography is a powerful tool for determining the three-dimensional structure of small molecules and proteins with atomic scale resolution. However, the process of producing diffraction quality crystals remains a major bottleneck in structure determination. Optically induced localised heating and consequent crystallisation method is one of the emerging technique to crystallise small molecules and proteins due to the non-contact nature as well as ability to externally control the parameters such as laser wavelength and intensity. In this work, several small molecule compounds were crystallised using an experimental setup built around an inverted Nikon microscope together with a CW Nd:YAG laser ( = 1064 nm) as an optical source.
