Deep Sea Microbes Shed Light on Human Biology

(HealthDay News) -- By studying microbes that live near the boiling thermal vents of the deep sea, scientists have identified the structure of an RNA and protein enzyme that is key to making human ribosomes, new research shows.

Ribosomes, a component of all cells that have a nucleus, are responsible for translating the information encoded in DNA into proteins that are crucial for biological processes.

In their study, researchers from Yale University studied Methanocaldococcus jannaschii, a microbe considered an "extremophile" because it thrives in harsh conditions, including in Antarctic ice and at the bottom of the ocean.

Using single-particle electron microscopy, the study authors described the structure of "box C/D small ribonucleoproteins," which are essential to making ribosomes. Read more...
