Unique ID: D011088
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D011088
Annotation: do not confuse entry term POLYDEOXYRIBONUCLEOTIDE SYNTHETASES with entry term POLYRIBONUCLEOTIDE SYNTHETASE
Scope Note: Poly(deoxyribonucleotide):poly(deoxyribonucleotide)ligases. Enzymes that catalyze the joining of preformed deoxyribonucleotides in phosphodiester linkage during genetic processes during repair of a single-stranded break in duplex DNA. The class includes both EC 6.5.1.1 (ATP) and EC 6.5.1.2 (NAD).
Entry Term(s): DNA Joinases; DNA Ligase; Polydeoxyribonucleotide Ligases; Polydeoxyribonucleotide Synthetases; T4 DNA Ligase
Registry Number: EC 6.5.1.-
