Generalities Function Deubiquitinases or Deubiquitinating enzymes (DUBs) are key enzymes belonging to the vast group of proteases, allowing the degradation of ubiquitin of proteins. These enzymes are thus implicated in the regulation of protein degradation. Indeed, when a protein is going to be degraded, an enzymatic cascade will add a poly-ubiquitin fragment to the protein. This mechanism is called ubiquitination.[1] Following this step, mono or poly-ubiquitin is removed from the protein which has been degraded, by deubiquitinase. Families So far, six structural families of DUBs have been discovered. Of these, five belong to the protease family and the last is a family of zinc-dependent metallo-proteases. These enzymes do not play the same role during post-translational modifications : most families allow the removal of one of their substrates, ubiquitin, from the protein (USPs, OTUs, UCHs, Josephins, MINDYs, JAMMs, ULPs). While the Ub cascade family allows ubiquitin to be added to proteins and the UBDs family allow reading and therefore protein-ubiquitin recognition. Structural highlights This is a sample scene created with SAT to color by Group, and another to make a transparent representation of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
