Glutamyl kinase

L-Pro <3, 4, 5> (<3> enzyme from strain PAOl 5mM, 50% inhibition, complete inhibition at 30 mM, noncompetitive. Strain PAO 879, a proline-auxo-troph mutant lacks a proline-inhibitable y-glutamyl kinase [5] <4> 150 = 0.08 mM, at room temperature. At low temperatures the inhibition switches over into allosteric activation and the biosynthesis of proline is started [7] <4> feedback-inhibition [8]) [5, 7, 8, 10]... [Pg.352]

Additional information <2, 3> (<2> the concentration of glutamate which yields half-maximal activity is 33 mM for y-glutamyl kinase DHPr, and 37mM for y-glutamyl kinase w-l-, no typical Michealis-menten kinetics [2] <3> plots of the enzyme activity as a function of ATP concentration are non-hyperbolic [5]) [2, 5]... [Pg.353]
