| 摘要 |
The present invention provides beta-lactamase CD4+ T-cell epitopes, as well as novel variants that exhibit reduced immunogenic responses, as compared to the parental beta-lactamase. The present invention further provides DNA molecules that encode novel beta-lactamase variants, host cells comprising DNA encoding novel beta-lactamase variants, as well as methods for making beta-lactamases less immunogenic. In addition, the present invention provides various compositions that comprise these beta-lactamase variants that are less immunogenic than wild-type beta-lactamases.
