2.3.1.37 additional information - additional information - 486815, 486820, 486845 2.3.1.37 additional information - additional information kinetics analysis of wild-type and mutant enzymes, single and multiple turnover and stopped flow measurements, substrate protection study, overview 736116 2.3.1.37 additional information - additional information Michaelis-Menten steady-state kinetics, overview 735711 2.3.1.37 additional information - additional information Michaelis-Menten steady-state kinetics, two-step sequential kinetic mechanism , and thermodynamics. Both the reaction for wild-type hALAS2 and those for the X-linked protoporphyria variants comprised a single kinetic step associated with quinonoid intermediate formation followed by one decay step. Rates for the two steps range from 9.8-14.3/s and from 1.37-1.97 s for the reactions of the XLPP variants, whereas those for the wild-type hALAS2-catalyzed reaction are 6.6/s and 0.70/s 735684 2.3.1.37 additional information - additional information overview 486820 2.3.1.37 additional information - additional information pre-steady state and steady state kinetics, overview 736454 2.3.1.37 additional information - additional information pre-steady-state and steady-state kinetics of wild-type and mutant enzymes, stopped-flow measurements, single and mutiple turnover rates, equilibrium dissociation constants, binding isotherms, detailed overview 736491 2.3.1.37 0.00032 - glycine pH 7.5, 30°C, ALAS(K313A mutant)/ALAS 718696 2.3.1.37 0.00045 - glycine pH 7.5, 30°C, ALAS/ALAS 718696 2.3.1.37 0.00054 - butanoyl-CoA mutant R85L/T430V, pH 7.5, 30°C 706627
