RL   Submitted (MAR-2003) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Phosphorylates thymidine. ASFV replicates in the cytoplasm of
CC       infected cells and contains genes encoding a number of enzymes needed
CC       for DNA synthesis, including thymidine kinase. Important for growth in
CC       swine macrophages in vitro and is a virus virulence factor in swine (By
CC       similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + thymidine = ADP + dTMP + H(+); Xref=Rhea:RHEA:19129,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:17748, ChEBI:CHEBI:30616,
CC         ChEBI:CHEBI:63528, ChEBI:CHEBI:456216; EC=2.7.1.21;
CC   -!- SIMILARITY: Belongs to the thymidine kinase family. {ECO:0000305}.
