RT "EvidentialGene: Evidence-directed Construction of Genes on Genomes.";
RL Submitted (MAR-2016) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the reversible phosphorolysis of thymidine. The
CC produced molecules are then utilized as carbon and energy sources or in
CC the rescue of pyrimidine bases for nucleotide synthesis.
CC {ECO:0000256|PIRNR:PIRNR000478}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=phosphate + thymidine = 2-deoxy-alpha-D-ribose 1-phosphate +
CC thymine; Xref=Rhea:RHEA:16037, ChEBI:CHEBI:17748, ChEBI:CHEBI:17821,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:57259; EC=2.4.2.4;
CC Evidence={ECO:0000256|PIRNR:PIRNR000478};
CC -!- PATHWAY: Pyrimidine metabolism; dTMP biosynthesis via salvage pathway;
CC dTMP from thymine: step 1/2. {ECO:0000256|PIRNR:PIRNR000478}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738,
CC ECO:0000256|PIRNR:PIRNR000478}.
CC -!- SIMILARITY: Belongs to the thymidine/pyrimidine-nucleoside
CC phosphorylase family. {ECO:0000256|ARBA:ARBA00006915,
CC ECO:0000256|PIRNR:PIRNR000478}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:KZS17385.1}.
