- Couple RNA single strands by bridging oligonucleotide adapters
생화학적/생리학적 작용
T4 DNA Ligase forms an energy dependent phosphodiester linkage between the termini of adjacent polynucleotides of duplex DNA. The ligation reaction requires ATP as a cofactor. Ligation of blunt-ended fragments requires higher enzyme concentration and can be facilitated by using PEG in the reaction mixture. The enzyme requires a 3′ hydroxyl and 5′ phosphate for ligation. Self-ligation of vector DNA can be prevented by dephosphorylation with alkaline phosphatase. T4 ligase plays an active role in repair of DNA and RNA nicks.
성분
T4 DNA Ligase is supplied in a solution containing 20 mM Tris-HCl (pH 7.5), 50 mM KCl, 1 mM DTT, and 50% (v/v) glycerol.
단위 정의
One Weiss unit is defined as the amount of enzyme required to catalyze the exchange of 1 nmole of P32 from pyrophosphate into ATP as Norit-absorbable material in 20 minutes at 37°C.
기타 정보
T4 DNA Ligase is inactivated by heating at 65 °C for 10 minutes.

A series of 2,6-disubstituted aminoalkoxypyrimidine carboxamides (AAPCs) with potent inhibition of bacterial NAD(+)-dependent DNA ligase was discovered through the use of structure-guided design. Two subsites in the NAD(+)-binding pocket were explored to modulate enzyme inhibitory potency: a hydrophobic selectivity region
