1.1.1.88 additional information - additional information kinetic analysis, overview. The enzyme exhibits positive cooperativity toward the substrates of the reductive reaction, but the oxidative reaction exhibits unusual double-saturation kinetics, distinctive among characterized HMG-CoA reductases. The unusual kinetics may arise from the presence of multiple active oligomeric states, each with different Vmax values 740104 1.1.1.88 0.00734 - 3-hydroxy-3-methylglutaryl-CoA at pH 7.4, temperature not specified in the publication 760594 1.1.1.88 0.0285 - NADH at pH 7.4, temperature not specified in the publication 760594 1.1.1.88 0.03 - CoASH H381A mutant, oxidative acylation of mevalonate 287502 1.1.1.88 0.032 - NADH reductive deacylation to mevalonate 287496, 287497 1.1.1.88 0.039 - CoA oxidative acylation of mevalonate 287496, 287497 1.1.1.88 0.046 - CoA mevaldate oxidation 287496, 287497 1.1.1.88 0.05 - CoASH oxidative acylation of mevalonate 287499 1.1.1.88 0.05 - CoASH wild-type enzyme, oxidative acylation of mevalonate 287502 1.1.1.88 0.05 - DL-3-hydroxy-3-methylglutaryl-CoA reductive deacylation to mevalonate 287496, 287497
