mcbABCD

This part produces an antibiotic originated from Escherichia coli that targets a bacterial topoisomerase, DNA gyrase.

Background:

Here, we tried to improve the former antimicrobial peptide(mccb17) expressing system of 2019 Fudan BBa_K3245010. By dividing into the peptide expressing parts and the immunity parts, we wanted to firstly test whether the polycistron could work properly and separately, then manipulate their expression level with more efficiency.

Design:

This part is an antibiotic coding gene cluster with leader peptide and proteins for its maturation.

Further Application

For futher application, this part is provided as an antimicrobial peptide(mccb17) expressing example and are effective for a wide range of microbes. This part can be used together with BBa_K3606004 to provide immunity for the engineered strain and create survival advantage. These part are especially useful to be expressed in vivo because research has proved that it can also ease the inflammation in intestine by limiting the expansion of related pathogens and pathobionts.
