MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression through RNA interference. Human miRNAs are generated through a series of enzymatic processing steps. The precursor miRNA (pre-miRNA) is recognized and cleaved by a complex containing Dicer and several non-catalytic accessory proteins. HIV TAR element binding protein (TRBP) is a(More)
Ensuring the correct folding of RNA molecules in the cell is of major importance for a large variety of biological functions. Therefore, chaperone proteins that assist RNA in adopting their functionally active states are abundant in all living organisms. An important feature of RNA chaperone proteins is that they do not require an external energy source to(More)
Snake venom metalloproteinases (SVMPs) participate in snakebite pathology such as hemorrhage, inflammation, and necrosis. They are synthesized as latent multi-domain precursors whose processing generates either catalytically active enzymes or free non-enzymatic domains. Recombinant expression of the precursor of P-III class SVMPs has failed due to the(More)
Small angle neutron scattering (SANS) is a powerful technique for investigating association states and conformational changes of biological macromolecules in solution. SANS is of particular interest for the study of the multi-component systems, as membrane protein complexes, for which in vitro characterisation and structure determination are often(More)
