CC -!- FUNCTION: The enzymes which catalyze the reversible phosphorolysis of
CC pyrimidine nucleosides are involved in the degradation of these
CC compounds and in their utilization as carbon and energy sources, or in
CC the rescue of pyrimidine bases for nucleotide synthesis.
CC {ECO:0000256|HAMAP-Rule:MF_01628}.
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|ARBA:ARBA00000749, ECO:0000256|HAMAP-
CC Rule:MF_01628};
CC -!- PATHWAY: Pyrimidine metabolism; dTMP biosynthesis via salvage pathway;
CC dTMP from thymine: step 1/2. {ECO:0000256|HAMAP-Rule:MF_01628}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738, ECO:0000256|HAMAP-
CC Rule:MF_01628}.
CC -!- SIMILARITY: Belongs to the thymidine/pyrimidine-nucleoside
CC phosphorylase family. {ECO:0000256|ARBA:ARBA00006915,
CC ECO:0000256|HAMAP-Rule:MF_01628}.
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:EKT53632.1}.
