I wonder what all those democrats and republicans who run this country and don’t believe in evolution would have to say about this? Probably the same derp they said when a biologist tried to explain the e. coli vitamin c example of evolution in a lab.
There’s a wobbly new biochemical structure in Burckhard Seelig’s lab at the University of Minnesota that may resemble what enzymes looked like billions of years ago, when life on earth began to evolve – long before they became ingredients for new and improved products, from detergents to foods and fuels.
Seelig created the fledgling enzyme by using directed evolution in the laboratory. Working with colleague Gianluigi Veglia, graduate student Fa-An Chao, and other team members, he subsequently determined its structure, which made its debut December 9 as an advance online publication in Nature Chemical Biology. Lab tests show that the enzyme (a type of RNA ligase, which connects two RNA molecules) functions like natural enzymes although its structure looks very different and it is flexible rather than rigid. Seelig speculates the new protein resembles primordial enzymes, before their current structures evolved.
3-D structure of the evolved enzyme (an RNA ligase)…
