The Takeaway

In the microscopic world, chemical warfare is constant, and Burkholderia bacteria have just revealed a genius new weapon called flavophos. This molecule is a perfect "fake" version of a substance the cell needs to make essential B-vitamins. When a rival bacterium takes the bait, it accidentally shuts down its own metabolism and starves to death. It’s an incredibly precise way to "hack" a competitor’s biological hardware. For us, this discovery could lead to a new class of antibiotics that kill "superbugs" by tricking them into committing metabolic suicide.

From the abstract

Phosphonate natural products have proven value to society as antibiotics and herbicides, and inhibit a range of enzyme targets usually by mimicking the enzyme substrates. In this study, we investigate a family of phosphonate biosynthetic gene clusters (BGCs) found in Burkholderia. Heterologous expression in Escherichia coli resulted in production of an antimicrobial compound. Spectroscopic characterization and chemical synthesis assigned its structure as 2,4-dioxopentylphosphonic acid. One of th
