| Description |
Superoxide dismutase (SOD) is a critical enzyme associated with controlling oxygen toxicity arising out of
oxidative stress in any living system. A hyper-thermostable SOD isolated from a polyextremophile higher
plant Potentilla atrosanguinea Lodd. var. argyrophylla (Wall. ex Lehm.) was engineered by mutation of a
single amino acid that enhanced the thermostability of the enzyme to twofold. The engineered enzyme was
functional from sub-zero temperature to .506C, tolerated autoclaving (heating at 1216C, at a pressure of
1.1 kg per square cm for 20 min) and was resistant to proteolysis. The present work is the first example to
enhance the thermostability of a hyper-thermostable protein and has potential to application to other
proteins for enhancing thermostability.
