^e[C]_0.5 - Ki	37 - 497	31 - 490

^a Peak PAH enzyme activity is given as [pmol L-tyrosine/min x mg protein].

^b L-phenylalanine concentration at peak activity is given as [µM].

^c [S]_0.5 - Ki indicates the optimal PAH working range (>50 % of the respective residual activity) as to substrate concentrations.

^d BH4 concentration at peak activity is given as [µM]

^e [C]_0.5 - Ki indicates the optimal PAH working range (>50 % of the respective residual activity) as to cofactor concentrations.

n. a., not applicable because no peak area was delimitable.
