CC   -!- FUNCTION: Catalyzes the pyrimidine ring opening between N-3 and C-4 by
CC       an unusual flavin hydroperoxide-catalyzed mechanism, adding oxygen
CC       atoms in the process to yield ureidoacrylate peracid, that immediately
CC       reacts with FMN forming ureidoacrylate and FMN-N(5)-oxide. The FMN-
CC       N(5)-oxide reacts spontaneously with NADH to produce FMN. Requires the
CC       flavin reductase RutF to regenerate FMN in vivo.
CC       {ECO:0000250|UniProtKB:P75898}.
