In-Silico - Comparative Growth Analysis of Wild type vs PR Transformed cells
(Metabolic Modeling using Constraint Based Reconstruction and Analysis)
Hypothesis
-
Increase in growth rate due to the proton efflux generated by Proteorhodopsin in minimal carbon media
Model Design
Reconstruction and Mathematical Modeling of E.coli K12-MG1655 pathway with Proteorhodopsin. Literature data:- Genome scale metabolic model thermodynamic data for genome scale E.coli K-12 MG1655 was derived. This was done by alignment with genomic annotation and the metabolic content of EcoCyc, characterization and quantification of biomass components and maintenance requirements of cell required for growth of the cell and thermodynamic data for reactions[1].
- Reconstruction of the pathway was carried out to suit our project, hence involving the effects due to Proteorhodpsin pumping activity. Data for pH gradient [2], the delta [H+] [3] was taken from literature and hence flux was calculated to formulate a comprehensive model.
