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 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...	nmrlearner	Journal club	0	08-13-2011 02:47 AM
