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. {ECO:0000255|HAMAP-
CC       Rule:MF_01699}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=FMNH2 + NADH + O2 + uracil = (Z)-3-ureidoacrylate + FMN + H(+)
