‘This Grand fir sesquiterpene synthase represents the ultimate in promiscuous enzymes,’said Yoshikuni. ‘We were able to encode to take it and construct seven specific and active enzymes. These seven enzymes use different reaction pathways to products, as diverse as they as diverse as they are from each other. ‘.. Idea idea, divergent evolution of his students worked with a type of a naturally occurring hydrocarbon compounds called sesquiterpenes, in a variety in a variety of products. For their model enzyme, they selected a sesquiterpene synthase by the Grand fir , which has produced the ability to a a variety of 52 sesquiterpenes from a single substrate.
The construction of the seven sesquiterpene synthases was carried out with the screening of less than 2500 mutants. An alterative approach, called directed evolution or molecular breeding, currently tested on other laboratories, requires the screening of tens of thousands to a million or more mutants.. In nature, the divergent evolution of promiscuous enzymes through trial and error through trial and error, much like the way in which the human immune system works. Several combinations of many different amino acid substitutions in promiscuous enzymes to a path that the desired result is found evolutionary reached tested. The amino acid substitutions, our methodology, reduce the molecular evolution called ‘plasticity residues.Added that mailings to criticize Va.
