The invention discloses a lyase of self-cleaving escherichia coli, and applications thereof. A brandnew lyase ClyN is constructed by adopting gene splicing means, the lyase can result in the self-cleaving of the host escherichia coli after being expressed in the escherichia coli, to release intracellularly expressed ATP and protein. Recombinant ClyN expression plasmid can be duplicated in the escherichia coli BL21(DE3), and express for 15 min under the induction of IPTG to observe the obvious phenomenon of inducing the escherichia coli to self-cleave, and the induced cleaving efficiency achieves 99.8%. When the host bacteria express heterologous enhanced green fluorescent protein (EGFP), EGFP can be released in solution after escherichia coli is cleaved, and the release efficiency is 89% of direct ultrasonic breaking efficiency. Therefore, the ClyN can be used for extracting and release of heterologous protein after expression in the escherichia coli, thus having wide application prospects.
