Scientists blueprint tiny cellular 'nanomachine'
Tempe AZ (SPX) Dec 19, 2015
Scientists have drawn up molecular blueprints of a tiny cellular 'nanomachine', whose evolution is an extraordinary feat of nature, by using one of the brightest X-ray sources on Earth. The scientists produced the structural map of this nanomachine - diacylglycerol kinase - by using a "hit and run" crystallography technique. In doing so, they have been able to understand how the tiny enzyme performs critical cellular duties - answering questions that have been on the table for over 50 years about ... read more
