Kinetic analysis of the inhibition of MtP5CR by HEPES. Enzyme activity was measured at varying substrate concentrations in the presence of various inhibitor levels. Invariable substrates were fixed as in the standard mixture. Three replications were carried out for each treatment. Lines intersecting at the x-axis in the Lineweaver-Burk plots accounted for non-competitive inhibition types in all cases. Non-linear regression analysis of data [Michaelis-Menten fit, Lineweaver-Burk (double-reciprocal) transform, linear regression over Michaelis-Menten data, and non-competitive inhibition] was computed using Prism 6 for Windows, version 6.03.
