Description
*Pseudomonas aeruginosa* is an opportunistic human pathogen associated with the chronic infection of the lungs of Cystic Fibrosis patients – New Zealand’s most common lethal genetic disease. *P. aeruginosa* has an innate resistance to antibiotics and concerns exist around the appearance of multi-drug resistant strains [1].
The shikimate pathway is responsible for the biosynthesis of key aromatic metabolites including the aromatic amino acids phenylalanine, tyrosine, and tryptophan; folic acid; and, in the case of *P. aeruginosa*, the toxic secondary metabolite pyocyanin [2].
The determination of the crystal structure of a key enzyme in the shikimate pathway from *P. aeruginosa* reveals a distinct regulatory mechanism and provides only the second example of a crystal structure of this type of enzyme.
