WebJun 30, 2024 · First, the E1 enzyme forms a thioester bond between its active site Cys and the C-terminal Gly of ubiquitin in an ATP-dependent manner. Ubiquitin is then transferred on to the Cys residue in the active site of the E2 enzyme; E2 can bind to E3-ubiquitinated ligase after activation. WebOct 19, 2016 · The ubiquitin-proteasome system regulates numerous signaling functions and is a major mechanism for controlling protein homeostasis and developmental decisions. In this pathway, ubiquitin is transferred to its targets via an E1-E2-E3 cascade ( 6, 7 ).
