Phosphate hardly influences the kinetic profile diminishing the S0.5 constant value slightly to 8.1 mM. Addition into the medium of 1 mM adenine nucleotide, ADP or ATP, transforms the sigmoid-shaped profile of the control kinetic curve into a hyperbolic one, diminishing simultaneously the value of the S0.5 constant from 9.2 mM to 2.4 mM, respectively.
