Abstract
Simultaneous depletion of phenylalanine and tyrosine by phenylalanine ammonia lyase is described in a mutual competitive inhibition model. The enzymes obtained fromSporidiobolus pararoseus andRhodosporidium toruloides were charaterized in terms of stability, optimal reaction parameters and kinetic behaviour. Both enzymes followed Michaelis-Menten kinetics with respect to the two amino acids. However, the enzyme fromRhodosporidium toruloides was inhibited by high tyrosine concentrations.Keywords
