CC -!- FUNCTION: Thymidylate synthase required for de novo biosynthesis of
CC pyrimidine deoxyribonucleotides. Required for both nuclear and
CC mitochondrial DNA synthesis. {ECO:0000269|PubMed:17248617,
CC ECO:0000269|PubMed:334734, ECO:0000269|PubMed:4580573,
CC ECO:0000269|PubMed:6287238, ECO:0000269|PubMed:7028756}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6R)-5,10-methylene-5,6,7,8-tetrahydrofolate + dUMP = 7,8-
CC dihydrofolate + dTMP; Xref=Rhea:RHEA:12104, ChEBI:CHEBI:15636,
CC ChEBI:CHEBI:57451, ChEBI:CHEBI:63528, ChEBI:CHEBI:246422;
CC EC=2.1.1.45; Evidence={ECO:0000269|PubMed:7028756};
CC -!- ACTIVITY REGULATION: Inhibited by 5-fluoro-2'-deoxyuridine 5'-
CC monophosphate (FdUMP). {ECO:0000269|PubMed:6287238}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=5 uM for dUMP {ECO:0000269|PubMed:7028756};
CC KM=70 uM for 5,10-methylene-tetrahydropteroylglutamate
CC {ECO:0000269|PubMed:7028756};
CC pH dependence:
CC Optimum pH is 6.8-7.2. {ECO:0000269|PubMed:7028756};
CC -!- PATHWAY: Pyrimidine metabolism; dTTP biosynthesis.
CC -!- SUBUNIT: Homodimer. {ECO:0000269|PubMed:7028756}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:8132557}.
CC Note=Localizes to the nuclear periphery.
CC -!- INDUCTION: Transcribed in a periodic manner during the cell cycle with
CC maximal mRNA levels occurring just prior to the onset of DNA
CC replication. The promoter contains 8-base-pair motifs (ACGCGTNA) called
CC the MluI cell-cycle boxes (MCBs), which mediate transcription
CC regulation by SWI6. {ECO:0000269|PubMed:1297653,
CC ECO:0000269|PubMed:1409658, ECO:0000269|PubMed:1608451,
CC ECO:0000269|PubMed:3020375, ECO:0000269|PubMed:3522259}.
CC -!- SIMILARITY: Belongs to the thymidylate synthase family. {ECO:0000305}.
