CATH

CATH is a system used by scientists to classify and organize proteins based on their structure. It groups proteins into categories that share similar shapes and features, helping researchers understand their functions and relationships. The name CATH stands for Class, Architecture, Topology, and Homologous superfamilies—covering different levels of structural similarity. By classifying proteins this way, CATH aids in studying how proteins work, predicting functions of new proteins, and understanding their roles in biology and medicine. This organization turns complex protein structures into an accessible framework for scientific research.
