WebMay 16, 2024 · T4 PNK has a molecular weight of 132 kDa. It’s a tetramer of identical monomers with each having a molecular weight of 33 kDa and no kinetic cooperativity. … WebTypical amplification by PCR does not use phosphorylated primers. In this case, the 5' ends of the amplicon are non-phosphorylated, and need to be treated by a kinase, such as T4 Polynucleotide Kinase, to introduce the 5' phosphate.
WebMay 16, 2024 · T4 PNK has a molecular weight of 132 kDa. It’s a tetramer of identical monomers with each having a molecular weight of 33 kDa and no kinetic cooperativity. The dual roles—kinase and phosphatase—performed by the enzyme reside in … WebT4 DNA ligase is an enzyme that fixes broken DNA and seals it – similar to super glue. This particular DNA ligase was isolated from bacteriophage T4. During DNA replication or recombination, a break or a ‘nick’ in the backbone of DNA frequently occurs. Afterwards, the DNA ligase comes in and plays an important role on repairing these ...
WebJul 22, 2024 · We further engineered fusion enzymes containing both Pfu RNA ligase and T4 polynucleotide kinase. One fusion enzyme, 8H-AP, was thermostable and can directly catalyze 5'-OH-terminated DNA substrates to adenylated products. The newly discovered Pfu RNA ligase and the engineered fusion enzyme may be useful tools for applications … Web100u. ¥ 13,200. T4 Polynucleotide Kinase catalyzes the transfer of the γ-phosphate from ATP to the 5´-terminus of polynucleotides or to mononucleotides bearing a 5´-hydroxyl group. The enzyme may be used to phosphorylate RNA, DNA and synthetic oligonucleotides prior to subsequent manipulations such as ligation and cloning.
WebT4 RNA ligase 1 is used for ligation of ssRNA and DNA, RNA ligase–mediated rapid amplification of cDNA ends (RLM-RACE), ligation of oligonucleotide adapters to cDNA or single-stranded primer extension products for PCR, oligonucleotide synthesis, and various 5′ nucleotide modifications of nucleic acids.
