RutA has a central role in the Rut pathway, which is composed of seven proteins, all of which are required by Escherichia coli K-12 to grow on uracil as the sole nitrogen source
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
RutA is involved in the pyrimidine catabolic Rut pathway, which converts uracil to 3-hydroxypropionate or 2-methyl-3-hydroxypropionate. The flavoenzyme RutA, along with the flavin reductase RutF, catalyzes the initial uracil ring opening by an unprecedented oxidative hydrolysis reaction to give 3-ureidoacrylate
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

the pyrimidine ring is cleaved directly by adding a pair of oxygen atoms and producing ureidoacrylate peracid. This odd metabolite, a strong and highly toxic oxidizing agent, is reduced spontaneously, albeit slowly, to ureidoacrylate
(Z)-3-ureidoacrylic peracid decomposes nonenzymatically to form primarily (Z)-3-ureidoacrylic acid and uracil, half life of (Z)-3-ureidoacrylic peracid is 3 hours at pH 10.0 at 25°C and much less at lower pH
