Shape shifting in the control of protein function

May 28, 2020 | Duration: 1 hr 30 mins.

What roles do conformational changes play in regulating protein function? Protein shape change can be triggered by a variety of factors, including ligand binding, temperature or pH, and can alter enzyme activity and function, allowing enzymes to carry out different functions in different contexts. In this virtual event, researchers present their findings on proteins that undergo conformational changes including reassembly, oligomerization and fold-switching.

The talks in this virtual event were originally programmed to take place as an in-person Spotlight Session at the 2020 ASBMB Annual Meeting.
