Coenzyme A (CoA, CoASH, or HSCoA) is a coenzyme, notable for its role in the synthesis and oxidation of fatty acids, and the oxidation of pyruvate in the citric acid cycle. All genomes sequenced to date encode enzymes that use coenzyme A as a substrate, and around 4% of cellular enzymes use it (or a thioester, such as acetyl-CoA) as a substrate. In humans, CoA biosynthesis requires cysteine, pantothenate, and adenosine triphosphate (ATP).[1]
TaKaRa Taq DNA Polymerase is a versatile and thermostable polymerase suitable for a variety of standard PCR applications. The enzyme is also supplied as a Premix Taq DNA polymerase (Cat.#R004A), a 2X PCR master mix containing Taq enzyme, buffer and dNTPs.This premix formulation simplifies PCR setup and minimizes pipetting steps. This is particularly helpful for high-throughput screening projects.he enzyme is also supplied as a Premix Taq DNA polymerase (Cat. #R004A), a 2X PCR master mix containing Taq enzyme, buffer and dNTPs.
Taq makes DNA products that have A (adenine) overhangs at their 3' ends. This may be useful in TA cloning, whereby a cloning vector (such as a plasmid) that has a T (thymine) 3' overhang is used, which complements with the A overhang of the PCR product, thus enabling ligation of the PCR product into the plasmid vector.ne of Taq' s drawbacks is its lack of 3' to 5' exonuclease proofreading activity resulting in relatively low replication fidelity. Originally its error rate was measured at about 1 in 9,000 nucleotides.
