When one wants to modify an enzyme for a new function, as Matti Leisola explains in his new book, there are two ways to go about it.
The supposed sudden emergence of the enzyme nylonase has been a chief talking point for the power of evolution for many years.
Yesterday, I described how some biologists claim that the enzyme nylonase demonstrates that it is easy to get new functional proteins.
Some bacteria developed the ability to consume nylon. No need for ID in biology?
