CARMEN- Comparative Analysis and Reconstruction of MEtabolic Networks


KGML-based model generation


CARMEN provides the generation of KGML-based models derived from KEGG database information. They are combined with annotation data such as EC numbers, gene identifiers and gene names of a chosen organism. If there exists more than one annotated gene with identical EC number, CARMEN creates a new symbol for each of these genes close to each other. The generated metabolic networks are stored in the standardized SBML format to enable the subsequent editing and extension of chosen networks. This allows manual verification of pathways, which may get reconstructed in a semi-finished state in case of incomplete genome annotation data or database inconsistencies.

One application example is the reconstruction of the glycolysis pathway of Xanthomonas campestris pv. campestris B100 (Figure 1).

Beyond the basic KGML-based reconstruction, various options can be used to affect the output of the locally installable version of CARMEN:
