Introduction

Three of the proteins required in the project are cytochrome c proteins (haem proteins). Hence, the heme biosynthesis pathway needs to be modelled. Pathway of heme production in E. coli (C-5 pathway from glutamate)

Mathematical model

Pathway of heme production in E. coli (C-5 pathway from glutamate):
Also, d-Aminolevulinate (ALA) produced as an intermediate in the above reactions. -Aminolevulinate Synthase (ALA Synthase) is the committed step of the heme synthesis pathway, and is usually rate-limiting for the overall pathway. Regulation occurs through control of gene transcription. Heme functions as a feedback inhibitor, repressing transcription of the gene for -Aminolevulinate Synthase.
A non-competitive irreversible feedback inhibition model is assumed for this step with a Ki value of 0.02 mM. Hence, the following equation governs the production of ALA:



A non-competitive irreversible feedback inhibition model is assumed for this step with a ki value of 0.02 mM. Hence, the following equation governs the conversion to ALA:
