Intrinsically disordered proteins.
Our understanding of protein function has been predominated by the view that proteins need to adopt a defined three dimensional structure to be able to carry out their function. Indeed, crystal structures of numerous proteins have been instrumental in establishing the structure– function paradigm. For example, the structures of numerous enzymes have highlighted the need for particular chemical ...
متن کاملIntrinsically Disordered Proteins
In the same way that neither a messy lab bench nor a clean one is a reliable indicator of a researcher’s productivity, a protein’s function cannot be judged solely on the basis of its neatly folded and stable domains. As evidenced by recent work discussed in this Select, we are learning that intrinsically disordered regions feature in many of the cell’s most productive multitaskers, proteins wh...
متن کاملIntrinsically Disordered Proteins in Biomineralization
Intrinsically disordered proteins (IDPs) have the potential to play a unique role in the study of proteins and the relationships between structure and function. Intrinsic disorder affects chemical and cellular events such as cell signaling, macromolecular self-assembly, protein removal and crystal nucleation and growth. This chapter explores the structural principles by which IDPs act and revea...
متن کاملConstructing ensembles for intrinsically disordered proteins.
The relatively flat energy landscapes associated with intrinsically disordered proteins makes modeling these systems especially problematic. A comprehensive model for these proteins requires one to build an ensemble consisting of a finite collection of structures, and their corresponding relative stabilities, which adequately capture the range of accessible states of the protein. In this regard...
متن کاملImproving Sequence Alignments For Intrinsically Disordered Proteins
Here we analyze sequence alignments for intrinsically disordered proteins. For 55 disordered protein families we measure the performance of different scoring matrices and propose one adjusted to disordered regions. An iterative algorithm of realigning sequences and recalculating matrices is designed and tested. For each matrix we also test a wide range of gap penalties. Results show an improvem...
