Evolved sortases exhibiting enhanced reaction kinetics and/or altered substrate preferences are provided herein, for example evolved sortases that bind recognitions motifs comprising a LAXT or LPXS sequence. Also provided are methods (e.g., orthogonal transpeptidation and diagnostics methods) for using such sortases. Kits comprising materials, reagents, and cells for carrying out the methods described herein are also provided.
本文提供的进化分选酶具有增强的反应动力学和/或改变的底物偏好,例如,进化分选酶可结合由
LAXT 或 LPXS 序列组成的识别基团。还提供了使用此类分选酶的方法(如正交转肽和诊断方法)。还提供了包括材料、试剂和细胞的试剂盒,用于实施本文所述的方法。
