A new implemented version of program MIR (MIR II): analysis and identification of mathematical models in enzyme and transport kinetic studies

Abstract

The computer program MIR previously described (R. Bianchi, G.M. Hanozet and M. Pilone Simonetta, Comput. Prog. Biomed. 16 (1983) 189) that fits trial rate laws to enzyme and transport steady-state kinetic data by the least-squares method has been enhanced. The new version MIR II is an interactive program and it consists of five major routines and a larger number of smaller program elements to perform the linear (three different functional forms) and non-linear (eleven mathematical models) regression analysis of kinetic data from enzyme and transmembrane transport experiments, also in the presence of inhibitors. Other features of the new program include a set of statistics and tests useful for the model building process, for the development of the mathematical model and for its validation and maintenance. An algorithm for fitting a straight line taking into account errors in both x and y is also provided.
