Ubiquitin-conjugating enzymes

Ubiquitin-conjugating enzymes, or E2 enzymes, are proteins that play a key role in the process of tagging other proteins for degradation or regulation within cells. They work by attaching a small protein called ubiquitin to specific target proteins, signaling them for removal or modification. This process helps maintain cellular health by controlling protein levels and removing damaged or unneeded proteins. E2 enzymes act as intermediaries in this tagging system, working alongside other enzymes to ensure precise and efficient regulation of protein function and turnover.
