Abstract
We have determined the solution NMR structure of the intermembrane space domain (IMSD) of the human mitochondrial ATPase associated with various activities (AAA) protease known as AFG3-like protein 2 (AFG3L2). Our structural analysis and molecular dynamics results indicate that the IMSD is peripherally bound to the membrane surface. This is a modification to the location of the six IMSDs in a model of the full length yeast hexaoligomeric homolog of AFG3L2 determined at low resolution by electron cryomicroscopy [1]. The predicted protein-protein interaction surface, located on the side furthest from the membrane, may mediate binding to substrates as well as prohibitins.

Narrowing the conformational space sampled by two-domain proteins with paramagnetic probes in both domains
Abstract Calmodulin is a two-domain protein which in solution can adopt a variety of conformations upon reorientation of its domains. The maximum occurrence (MO) of a set of calmodulin conformations that are representative of the overall conformational space possibly sampled by the protein, has been calculated from the paramagnetism-based restraints. These restraints were measured after inclusion of a lanthanide binding tag in the C-terminal domain to supplement the data obtained...

Computational methods are powerful in capturing the results of experimental studies in terms of force fields that both explain and predict biological structures. Validation of molecular simulations requires comparison with experimental data to test and confirm computational predictions. Here we report a comprehensive database of NMR results for membrane...

One of the main mechanisms of membrane protein folding is by spontaneous insertion into the lipid bilayer from the aqueous environment. The bacterial toxin, colicin Ia, is one such protein. To shed light on the conformational changes...
