PhD abstract
Reconstructing the metabolic pathways of fully sequenced organisms is becoming a task of major importance and several approaches have already been proposed in order to help biologists in identifying and analysing the metabolic pathways of a newly sequenced organism.
A first approach relies on a database of already characterised metabolic pathways and the problem is then to find if each pathway of the database is present or not in the organism under study. This approach is clearly unable to predict unknown or alternative pathways and more exploratory approaches are needed.
What is called ab initio metabolic pathway reconstruction is the problem of finding a metabolic pathway connecting two or more compounds relying only on a database of feasible reactions. We propose a new formulation for the problem of the ab initio metabolic pathway reconstruction. Given a set of biochemical reactions together with their substrates and products, we consider the reactions as transfers of atoms between the chemical compounds and we look for sequences of reactions transferring a maximal (or preset) number of atoms between a given source and the sink compound. We state this problem as the one of finding a composition of partial injections that maximises the image size. The theoretical complexity of this problem has been studied and a practical algorithm to solve it is presented.
