CC   -!- FUNCTION: Catalyzes the Fe(2+) and alpha-ketoglutarate-dependent
CC       oxidation of pentalenolactone D to pentalenolactone F in the
CC       biosynthesis of pentalenolactone antibiotic. Also able to catalyze the
CC       oxidation of pentalenolactone D to pentalenolactone E.
CC       {ECO:0000269|PubMed:21250661}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 2-oxoglutarate + 2 O2 + pentalenolactone D = 2 CO2 + H2O +
CC         pentalenolactone F + 2 succinate; Xref=Rhea:RHEA:34579,

CC         ChEBI:CHEBI:70789; EC=1.14.11.36;
CC   -!- COFACTOR:
CC       Name=Fe(2+); Xref=ChEBI:CHEBI:29033; Evidence={ECO:0000250};
CC       Note=Binds 1 Fe(2+) ion per subunit. {ECO:0000250};
CC   -!- ACTIVITY REGULATION: Activated by ascorbate. {ECO:0000250}.
CC   -!- PATHWAY: Antibiotic biosynthesis; pentalenolactone biosynthesis.
CC       {ECO:0000269|PubMed:21250661}.
CC   -!- DISRUPTION PHENOTYPE: Accumulation of pentalenolactone D and lack of
CC       production of pentalenolactone as well as the precursors
CC       pentalenolactones E and F. {ECO:0000269|PubMed:21250661}.
CC   -!- SIMILARITY: Belongs to the TfdA dioxygenase family. {ECO:0000305}.
