General Information

EC Number General Information Comment Organism
1.14.99.46 metabolism RutA is the first enzyme of the pyrimidine catabolizing Rut pathway, the involved enzymes are encoded by the rut operon, including rutRABCDEFG and ydfG, overview. RutF functions as a flavin reductase that is required to regenerate the flavin mononucleotide, FMN, cofactor Escherichia coli
1.14.99.46 additional information the Rut pathway degrades exogenous pyrimidines as the sole nitrogen source at room temperature but not at 37°C, a restriction that is apparently a consequence of an inadequate ability to remove toxic malonic semialdehyde at the higher temperature, RutE/YdfG function. The catabolic pathway is highly expressed even in the absence of exogenous substrate and at 37°C Escherichia coli
3.5.1.110 metabolism RutB of the rut gene cluster is involved in the uracil catabolism, overview Escherichia coli
