Protein

Thymidine kinase

Gene

Ba71V-050

Organism
African swine fever virus (strain Badajoz 1971 Vero-adapted) (Ba71V) (ASFV)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Phosphorylates thymidine. ASFV replicates in the cytoplasm of infected cells and contains genes encoding a number of enzymes needed for DNA synthesis, including thymidine kinase. Important for growth in swine macrophages in vitro and is a virus virulence factor in swine (By similarity).By similarity

Catalytic activityi

ATP + thymidine = ADP + thymidine 5'-phosphate.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
