Creating enzymes through cell-free synthesis isn't the only thing this link below is about but personally I think its the most interesting part of it because I can imagine how doing that could be very useful and in several different ways;

@humy saidIt looks like this paper makes their enzymes in bacteria, but then uses them to synthesize HMG-CoA. It's a neat method in which they can tweak the reaction conditions in subtle ways to favor production of unique metabolites. Certainly, there is broad applicability as well as fundamental knowledge to be learned.
