Rewiring of metabolic pathways in E. coli for conversion amino acids to biofuels and ammonia. The rational design of catabolic pathways for amino acids leads to the accumulation of intracellular metabolites involving pyruvate, α-oxoglutarate, glutamate, and ammonia. The deleted genes are marked with “X”. OAA oxaloacetate, Pyr pyruvate, 2-KG α-oxoglutarate, KIV 2-ketoisovalerate, KIC 2-ketoisocaproate, KMV 3-ketomethylvalerate, iBOH isobutanol, 2-MB 3-methyl-1-butanol, 3MB 3-methyl-1-butanol
