CC   -!- FUNCTION: Dioxygenase that catalyzes the first step of DNA base J
CC       (beta-d-glucosyl-HOMedU) biosynthesis by converting thymine to 5-
CC       hydroxymethyluracil (HOMedU). DNA base J is a hypermodified thymidine
CC       residue found in the genome of kinetoplastid parasites, which is
CC       localized primarily to repetitive DNA, namely the telomeres, and is
CC       implicated in the regulation of antigenic variation. Also specifically
CC       binds to base J-containing DNA (J-DNA). Involved in propagation and
CC       maintenance of DNA base J synthesis initiated by JBP2 by specifically
CC       binding already synthesized DNA base J and propagating J synthesis.
CC       Thymine dioxygenase activity and J-DNA-binding are independent
CC       functions (By similarity). {ECO:0000250|UniProtKB:Q9U6M1}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-oxoglutarate + O2 + thymine = 5-hydroxymethyluracil + CO2 +
CC         succinate; Xref=Rhea:RHEA:10316, ChEBI:CHEBI:15379,
CC         ChEBI:CHEBI:16526, ChEBI:CHEBI:16810, ChEBI:CHEBI:16964,
CC         ChEBI:CHEBI:17821, ChEBI:CHEBI:30031; EC=1.14.11.6;
CC         Evidence={ECO:0000250|UniProtKB:Q9U6M1};
CC   -!- COFACTOR:
CC       Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC         Evidence={ECO:0000250|UniProtKB:Q6N021};
CC       Note=Binds 1 Fe(2+) ion per subunit. {ECO:0000250|UniProtKB:Q6N021};
CC   -!- SUBUNIT: Monomer. Binds to DNA as a monomer (By similarity).
CC       {ECO:0000250|UniProtKB:Q9U6M1}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9U6M1}.
CC   -!- DOMAIN: The DNA-binding JBP1 domain (DB-JBP1) is necessary and
CC       sufficient for binding to J-DNA. {ECO:0000250|UniProtKB:Q9U6M1}.
CC   -!- SIMILARITY: Belongs to the TET family. JBP1 subfamily. {ECO:0000305}.
