This part is an antibiotic coding gene cluster with proteins for MccB17 maturation.

Design:

Since we encountered difficulties in the expression of McbABCDEFG at the beginning, we decided to check whether the McbA/B/C/D/E/F/G genes can be expressed and translated separately. We successfully cloned McbG into the pGEX plasmid and transcribed it into BL21. After 5 hours of induction of McbG expression with IPTG, the whole protein SDS-PAGE was used to detect whether the McbG product was produced.

Results:

Figure 1. SDS-PAGE result. lane 1: mcbA lane 2: mcbA+IPTG lane 3: mcbE lane 4: mcbE+IPTG lane 5: mcbG lane 6: mcbG+IPTG lane 7: mcbBCD lane 8: mcbBCD+IPTG lane 9: pGEX+ IPTG

Comparing the 5th and 6th lanes, after IPTG induction, there is a clear band, which is the product of McbG expression.
