Your question is very general. There are many sorts of protein
engineering and design. Some, like the massive studies of barnase and
lysozyme are aimed atse seeing how mutations affect structure to
understand the underlying principles of structure. Others try to
mmodify a protein to give it a new function, for a variety of
purposes, including medical ones. Still another class of research
is on building entirely new sequences to fold into a desired structure
(de novo design), using either manual or automated methodologies. These
experiments test our overall understanding of protein structure, allow
us to explore regions of structure unavailable to nature, and may
haver material science or medical use.
All of these have had significant successes. Which do you want
to know more about?
