Question

A prokaryotic species is facing a new environmental stress
that can be ameliorated by a catalytic activity that requires
the side chain of a unique amino acid derivative called pyrovaline. How would such an organism develop a mechanism for the incorporation of this nonstandard amino acid
into an enzyme molecule? What would be the properties of
the molecules required to solve this problem?
