Changes in protein structure at the interface accompanying complex formation

IUCrJ, 2015
Protein interactions are essential in all biological processes. The changes brought about in the structure when a free component forms a complex with another molecule need to be characterized for a proper understanding of molecular recognition as well as

Allosteric mechanism of the V. vulnificus adenine riboswitch resolved by four-dimensional chemical mapping

eLife, 2018
The structural interconversions that mediate the gene regulatory functions of RNA molecules may be different from classic models of allostery, but the relevant structural correlations have remained elusive in even intensively studied systems.

RNA secondary structure prediction from multi-aligned sequences [PDF]

, 2013
It has been well accepted that the RNA secondary structures of most functional non-coding RNAs (ncRNAs) are closely related to their functions and are conserved during evolution.
