Fig. 1From: Reconstruction of a Genome Scale Metabolic Model of the polyhydroxybutyrate producing methanotroph Methylocystis parvus OBBPVenn diagrams representing the shared and unique reactions (a) and metabolites (b) of the GSMMs of Methylocystis parvus OBBP, Methylocystis hirsuta and Methylocystis sp. SC2. c The logarithms of the numbers (n) of metabolites participating in k reactions. The plot shows a typical scale free topology. d The same plot including only reactions that are active under optimal growth on methane, and their metabolitesBack to article page
