The arginine biosynthesis pathways in the strain SCM1 model. Genes for the first reaction (EC 2.3.1.1) in the normal arginine synthesis pathway (up part) is missing in the genome and thus a gap exists in the pathway. The existence of gene Nmar_1288 encoding ArgX that catalyzes the first step of the LysW-mediated arginine pathway (bottom part) suggests that strain SCM1 uses this pathway for arginine synthesis. Glu: l-glutamate; acglu: N-acetyl-l-glutamate; acg5p: N-acetyl-l-glutamate 5-phosphate; acg5sa: N-acetyl-l-glutamate 5-semialdehyde; acorn: N-acetylornithine; orn: l-ornithine; citr: l-citrulline; argsuc: N-(l-Arginino) succinate; arg: l-arginine; lysW-glu: LysW-l-glutamate; lysW-g5p: LysW-l-glutamyl 5-phosphate; lysW-g5sa: LysW-l-glutamate 5-semialdehyde; lysW-orn: LysW-l-ornithine
