Small changes to molecular structures can transform how reactions occur, but studying reaction mechanisms directly is difficult. ... Velocity maps of the S N 2 and E2 reaction mechanisms. a, ...

RING domain–containing E3 ligases promote the transfer of ubiquitin from the active site of an E2 to acceptor lysine residues on substrates, but the mechanism by which this occurs was unclear.

Lipidated Atg8, which is abundant in isolation membranes, is formed by Atg7 (E1), Atg3 (E2), and Atg12-Atg5-Atg16 complex (E3). This enzymatic reaction is called the lipidation reaction.

This enzymatic reaction is called the lipidation reaction. (c) When Atg8 lipidation reaction is performed on a prolate-shaped unilamellar membrane, the membrane morphology changes from a prolate shape ...
