Are you phishing for something or are you not sure how this actually works?
Everyone who is looking for proteins (vacines, medication) need to find the right proteins for different cases. For attaching to something (antibody design), for delivering something (like another protein) or for understanding a disease (why is this protein an issue?).
Are you asking what field of science or what industry is interested in predicting how proteins fold?
Biotechnology and medicine probably.
Pipeline from science to application sometimes takes decades, but I'm sure you can find news of some advancements enabled by finding out short, easy to synthesize proteins that fit particular receptor to block it or that process some simplified enzymes that still process some chemicals of interest more efficiently than natural ones. Finding them would be way harde without ability to predict how a sequence of amino-acids will fold.
You'd need to actually try to manufacture them then look at them closely.
First thing that came to my mind as a possible application is designing monoclonal antibodies. Here's some paper about something relating to alpha fold and antibodies:
