Disulfide Bond Design of Miniproteins
Miniproteins, also known as peptide therapeutics or constrained peptides, represent a promising class of molecules with diverse biomedical applications. These molecules are characterized by their compact size, high stability, and specific target binding, making them valuable platforms for drug development and biotechnological innovation. However, the inherent flexibility and susceptibility to degradation pose challenges in harnessing their full potential. At CD ComputaBio, we specialize in leveraging the power of artificial intelligence to revolutionize the design of disulfide bonds in miniproteins. Our innovative approach combines cutting-edge computational techniques with deep expertise in molecular biology to engineer miniproteins with enhanced structural stability, activity, and bioavailability.
