Structural insights into ADP-ribosylation of ubiquitin by Deltex family E3 ubiquitin ligases.

abstract：:Transcription factors control gene expression in all life. This raises the question of what is the smallest protein that can support such activity. In nature, Cro from bacteriophage λ is one of the smallest known repressors (66 amino acids), and activators are typically much larger (e.g., λ cI, 237 amino acids). Previ...
