Phenylalanine hydroxylase

[http://en.wikipedia.org/wiki/Phenylalanine_hydroxylase Phenylalanine hydroxylase (PAH)] is the enzyme that breaks down [http://en.wikipedia.org/wiki/Phenylalanine phenylalanine] to [http://en.wikipedia.org/wiki/Tyrosine tyrosine]. Deficiency of this enzyme activity results in the autosomal recessive disorder [http://en.wikipedia.org/wiki/Phenylketonuria phenylketonuria].#PAH1

PAH works well at a PH of around 7.0 (similar to the small intestine), and is denatured at temperatures above 30 degrees celsius (in experiments with gram-negative bacteria)#PAH2. The enzyme can be rendered protease resistant via full phosphorylation.#PAH3

Furthermore, the presence of oxygen and an additional cofactor (TPNH) is required for the hydrolysis to take place #PAH4.

Note that this part only works on gram-negative bacteria.
