I've tried looking around, and have had trouble researching this subject. Anyone know a site where they describe the various methods used by protein chemists to engineer new medicines?

I would suggest talking to a professor of pharmacology at a university. Below are a few specific searches you can browse for info.

If you're having trouble finding information about the various methods used by protein chemists to engineer new medicines, here are a few suggestions:

1. Look for online resources or articles that specifically discuss "designer proteins" and their applications in medicine. You can search for this term using search engines like Google. For example, you can try searching for "'designer proteins' medicine" or "'designer proteins' drugs" to find relevant information.

2. Explore scientific journals and databases for articles related to protein engineering and drug discovery. PubMed is a popular database for biomedical literature, and you can search for keywords such as "protein engineering," "drug discovery," or "designer proteins" to find relevant articles.

3. Consider reaching out to experts in the field, such as professors of pharmacology or researchers who specialize in protein engineering. They may be able to provide you with more specific information or point you towards valuable resources.

Remember that researching a specific topic can sometimes be challenging due to the technical nature of the subject. It may require thorough searching and exploration of different sources to find the information you need.
