The family of ubiquitin‐conjugating enzymes (E2s): deciding between life and death of proteins
Abstract
The family of ubiquitin‐conjugating (E2) enzymes is characterized by the presence of a highly conserved ubiquitin‐conjugating (UBC) domain. These domains accommodate the ATP‐activated ubiquitin (Ub) or ubiquitin‐like (UBL) protein via a covalently linked thioester onto its active‐site residue. E2 enzymes act via selective protein‐protein interactions with the E1 αnd E3 enzymes and connect activation to covalent modification. By doing so, E2s differentiate effects on downstream substrates, either with a single Ub/UBL molecule or as a chain. While E3s are involved in substrate selection, E2s are the main determinants for selection of the lysine to construct ubiquitin chains, which thereby directly control the cellular fate of the substrate. In humans, 35 active E2 enzymes have been identified so far, while other eukaryotic genomes harbor 16 to 35 E2 family members. Some E2s possess Nand/or C‐terminal extensions that mediate E2‐specific processes. During the past two decades, strong support has led to the control of E2 enzymes in decisions concerning the life or death of a protein. Here, we summarize current knowledge and recent developments on E2 enzymes with respect to structural characteristics and functions. From this we propose a shelllike model to rationalize the selectivity of these key enzymes in directing Ub/UBL‐conjugation pathways.— Van Wijk, S. J. L., Timmers, H. T. M.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
