Protein engineering.
The techniques of protein engineering are proving to be a revolutionary experimental tool for understanding protein structure-function relationships. Even at this early stage, proteins of improved characteristics for specific industrial and therapeutic uses have already been produced. Tailoring enzymatic properties for non-physiological substrate conditions, altering pH optima, changing substrate specificity, and improving stability have already been demonstrated to be feasible. Nevertheless, the ability to make useful proteins which radically differ from a natural structure or designing altogether new structures exceeds present understanding.
