Figure 2From: Bioinformatic evaluation of L-arginine catabolic pathways in 24 cyanobacteria and transcriptional analysis of genes encoding enzymes of L-arginine catabolism in the cyanobacterium Synechocystis sp. PCC 6803Schematic presentation of putative L-arginine-degrading pathways in cyanobacteria with the corresponding enzymes, intermediate metabolites, and final products. Numbering of enzymes refers to the one used in Table 3, 4, and 5–9.Back to article page
