Distribution of reactions and gene products in iRsp1095. (A) The pie chart depicts the subsystem distribution of the reactions in iRsp1095, with the percent contribution of each subsystem of reactions indicated in the corresponding section of the chart. It can be seen that amino acid, carbohydrate and nucleotide metabolism dominate the enzymatic reactions present in iRsp1095, while photosynthesis related reactions represent a smaller but significant fraction. (B) The bar chart depicts the distribution of gene products in iRsp1095 based on COG classification with the percent coverage shown for each class. Only COG classes significantly enriched for proteins present in the model (p < 0.01, hypergeometric distribution) are shown.
