A microscopic topographic map of cellular function

The flow of traffic through our nation's highways and byways is meticulously mapped and studied, but less is known about how materials in cells travel. Now, a team of researchers is challenging prior theories about how material leaves the inside of an E.coli cell. This discovery could have important implications for how we treat diseases.

Biotechnology construction kit for custom-designed products

Microorganisms often assemble natural products similar to product assembly lines. Certain enzymes, non-ribosomal peptide synthetases, play a key role in this process. Biotechnologists have now succeeded in changing these enzymes so that entirely new natural products, or even libraries of natural products, can be produced by microorganisms.
