Earliest Life Forms' Operation Promises Therapies for Diseases

In this article they talk about how the evolution of bacteria, one of the earliest life forms, has shed important perspective on potential therapies for some common diseases.  It has been recently discovered that the gas nitric oxide plays a fundamental regulatory role in regulating bacterial function, via a signaling mechanism called S-nitrosylation, which binds nitric oxide to protein molecules. The article also talks about how the researchers discovered a novel set of 150 genes that regulate S-nitrosylation production. They are using these new discoveries to help to treat/cure certain diseases.
