Abstract
The cellular process by which the protein ubiquitin (Ub) is covalently attached to a protein substrate involves Ub activating (E1s) and conjugating enzymes (E2s) that work together with a large variety of E3 ligases that impart substrate specificity. The largest family of E3s is the Cullin-RING ligase (CRL) family which utilizes a wide variety of substrate receptors, adapter proteins, and cooperating ligases. Cryo-electron microscopy (cryoEM) has revealed a wide variety of structures which suggest how Ub transfer occurs. Hydrogen deuterium exchange mass spectrometry (HDXMS) has revealed the role of dynamics and expanded our knowledge of how covalent NEDD8 modification (neddylation) activates the CRLs, particularly by facilitating cooperation with additional RING-between-RING ligases to transfer Ub.
期刊介绍：
Current Opinion in Structural Biology (COSB) aims to stimulate scientifically grounded, interdisciplinary, multi-scale debate and exchange of ideas. It contains polished, concise and timely reviews and opinions, with particular emphasis on those articles published in the past two years. In addition to describing recent trends, the authors are encouraged to give their subjective opinion of the topics discussed.
In COSB, we help the reader by providing in a systematic manner:
1. The views of experts on current advances in their field in a clear and readable form.
2. Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.
[...]
The subject of Structural Biology is divided into twelve themed sections, each of which is reviewed once a year. Each issue contains two sections, and the amount of space devoted to each section is related to its importance.
-Folding and Binding-
Nucleic acids and their protein complexes-
Macromolecular Machines-
Theory and Simulation-
Sequences and Topology-
New constructs and expression of proteins-
Membranes-
Engineering and Design-
Carbohydrate-protein interactions and glycosylation-
Biophysical and molecular biological methods-
Multi-protein assemblies in signalling-
Catalysis and Regulation
