Chain A,B   (DNK_DROME | Q9XZT6)
molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0019136    deoxynucleoside kinase activity    Catalysis of the reaction: ATP + 2'-deoxynucleoside = ADP + 2'-deoxynucleoside 5'-phosphate.
    GO:0016301    kinase activity    Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule.
    GO:0019206    nucleoside kinase activity    Catalysis of the reaction: ATP + nucleoside = ADP + nucleoside monophosphate.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
    GO:0004797    thymidine kinase activity    Catalysis of the reaction: ATP + thymidine = ADP + thymidine 5'-phosphate.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0071897    DNA biosynthetic process    The cellular DNA metabolic process resulting in the formation of DNA, deoxyribonucleic acid, one of the two main types of nucleic acid, consisting of a long unbranched macromolecule formed from one or two strands of linked deoxyribonucleotides, the 3'-phosphate group of each constituent deoxyribonucleotide being joined in 3',5'-phosphodiester linkage to the 5'-hydroxyl group of the deoxyribose moiety of the next one.
    GO:0006230    TMP biosynthetic process    The chemical reactions and pathways resulting in the formation of TMP, ribosylthymine monophosphate.
    GO:0006139    nucleobase-containing compound metabolic process    Any cellular metabolic process involving nucleobases, nucleosides, nucleotides and nucleic acids.
    GO:0006165    nucleoside diphosphate phosphorylation    The process of introducing a phosphate group into a nucleoside diphosphate to produce a nucleoside triphosphate.
    GO:0046939    nucleotide phosphorylation    The process of introducing one or more phosphate groups into a nucleotide to produce a phosphorylated nucleoside.
    GO:0016310    phosphorylation    The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005739    mitochondrion    A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
