Abstract:
Cyanobacteria represent an attractive source of natural bioactive compounds, ranging from sunscreens to cancer treatments. While many biosynthetic gene clusters (BGCs) that encode cyanobacterial natural products are known, the slow growth and lack of genetic tools in the native producers hampers their modification, characterization, and large-scale production. By engineering heterologous hosts for the expression of cyanobacterial BGCs, sufficient material can be produced for research or industry. Although several hosts have been evaluated for the expression of cyanobacterial natural products, this work details the process of expressing BGCs in Escherichia coli via promoter exchange.
