    摘要: The present invention provides methods for engineering proteins to optimize their performance under certain environmental conditions of interest. In some embodiments, the present invention provides methods for engineering enzymes to optimize their catalytic activity under particular environmental conditions. In some preferred embodiments, the present invention provides methods for engineering enzymes to optimize their catalytic activity and/or stability under adverse environmental conditions. In some preferred embodiments, the present invention provides methods for engineering enzymes to optimize their storage stability, particularly under adverse environmental conditions. In some preferred embodiments, the present invention provides methods for altering the net surface charge and/or surface charge distribution of enzymes (e.g., metalloproteases) to obtain enzyme variants that demonstrate improved performance and/or stability in detergent formulations as compared to the starting or parent enzyme.
