comments
This enzyme has an allosteric site, to which tryptophan (for activation) or tyrosine (for inhibition) is bound. The site is separate from the active site.
According to the literature [9] & [14], this enzyme catalyzes Claisen rearrangement or concerted addition and elimination.
According to the literature [7], [9] & [14], Glu246 can be mutated to glutamine residue, as it is a glutamine residue in the counterparts of E. coli and bacteria. Although the wild-type enzyme has an optimum in acidic pH, E246Q mutant has catalytic activity over a broad pH range (see [14]).
