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   -!- 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   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the thymidine/pyrimidine-nucleoside
CC       phosphorylase family. {ECO:0000305}.
