Nature's Antibiotic Factory

Vancouverite writes "The genome of Streptomyces coelicolor is unveiled and published in Nature. It and its relatives produce two-thirds of the natural antibiotics in use, including tetracycline and erythromycin, plus other pharmaceuticals such as anticancer agents and immunosuppresssants."

Re:It certainly is an exciting one

[diaphanous]

(1) nobody seems to have noticed or mentioned here that DNA is not the only way of inheriting cellular information

This seems like a trivial statement, though underemphasized in the popular media. Any organelle or chemical that is passed from parent to progeny is "cellular information"

(2) we are still borrowing microbes to do the actual manufacturing, rather than doing it mechanically ourselves.

Microbes have had billions of years more than homo sapiens to "discover" and test new anti biotics, it would be remarkable if we had surpassed them in cleverness in the few centuries we've studied them. We have gotten better at somethings though; 16 years ago if you wanted to clone a gene, the typical way to do it was to insert it into the E. coli genome, wait for the bacteria to divide several times and harvest the dna. Now its often done using polymerase chain reaction (though this does still require using a DNA polymerase from a thermophile, so we can't quite declare independence from the rest of nature.)
