Abstract:

Studies on the thermokinetic properties of model compound of Purple acid phosphatases (Na2[Fe2(μ-O)(μ-OAC)2(IDA)2].5H2O) hydrolysis of ATP, at 37℃, pH=6.0 by using LKB-2107 Batch microcalorimentry system. The Michaelis constant Km=(2.898 ± 0.195)×10-4mol•L-1 and rate constant k2=(4.617±0.193)×10-3•s-1 have been determined. The result has been discussed.

Key words: Thermokinetic, Microcalorimetry, ATP, Hydrolysis
