ENZYME: 1.14.99.46

Entry

EC 1.14.99.46               Enzyme

Name

pyrimidine oxygenase;
rutA (gene name)

Class

Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
Miscellaneous

Sysname

uracil,FMNH2:oxygen oxidoreductase (uracil hydroxylating, ring-opening)

Reaction(IUBMB)

(1) uracil + FMNH2 + O2 + NADH = (Z)-3-ureidoacrylate + H2O + FMN + NAD+ + H+ (overall reaction) [RN:R12544];
(1a) FMNH2 + O2 = FMN-N5-peroxide [RN:R12756];
(1b) uracil + FMN-N5-peroxide = (Z)-3-ureidoacrylate + FMN-N5-oxide [RN:R12545];
(1c) FMN-N5-oxide + NADH = FMN + H2O + NAD+ + H+ (spontaneous) [RN:R12539];
(2) thymine + FMNH2 + O2 + NADH = (Z)-2-methylureidoacrylate + H2O + FMN + NAD+ + H+ (overall reaction) [RN:R12546];
(2a) FMNH2 + O2 = FMN-N5-peroxide;
(2b) thymine + FMN-N5-peroxide = (Z)-2-methylureidoacrylate + FMN-N5-oxide [RN:R12547];
(2c) FMN-N5-oxide + NADH = FMN + H2O + NAD+ + H+ (spontaneous)

Reaction(KEGG)

R12539 R12544 R12545 R12546 R12547 R12756;
(other) R09936 R09937

Substrate

uracil [CPD:C00106];
FMNH2 [CPD:C01847];
O2 [CPD:C00007];
NADH [CPD:C00004];
FMN-N5-peroxide [CPD:C22379];
FMN-N5-oxide [CPD:C22238];
thymine [CPD:C00178]

Product

(Z)-3-ureidoacrylate [CPD:C20254];
H2O [CPD:C00001];
FMN [CPD:C00061];
NAD+ [CPD:C00003];
H+ [CPD:C00080];
FMN-N5-peroxide [CPD:C22379];
FMN-N5-oxide [CPD:C22238];
(Z)-2-methylureidoacrylate [CPD:C20256]

Comment

The enzyme participates in the Rut pyrimidine catabolic pathway. The flavin-N5-oxide that is formed by the enzyme reacts spontaneously with NADH to give oxidized flavin, releasing a water molecule.
