How can you use “ligase” in a sentence? Here are some example sentences to help you improve your vocabulary:
In A. thaliana , CSN was shown to be required for the efficient nuclear accumulation of the putative RING-type ubiquitin ligase COP1 [ 24], which mediates ubiquitin-dependent degradation of the photomorphogenic transcription factor HY5 [ 25].
Single nucleotide discrimination is achieved at the ligation step by the use of the thermostable DNA ligase, Ampligase, which has a high affinity for a perfectly matched substrate at the 3' end of a DNA molecule [ 17 ] . We were able to enhance allele discrimination at the ligation step by designing the OCP such that the 5' complementary region is firmly hybridized to the target sequence whereas the 3' region is in equilibrium with its target at the ligation temperature [ 12 ] . This would result in increased specificity since the correctly matched OCP will have a greater chance to act as substrate for the ligase.
2A), Pcu3p-associated ubiquitin ligase activity recovered from this mutant showed a much more dramatic increase (Fig.
The correlation coefficient between amplified and unamplified sample and the yield of aRNA amplified without DNA ligase are high enough to suggest that DNA ligase activity is not necessary for RNA amplification in microarray analysis.
For example, Herschlag and co-workers have previously shown that a nucleobase could complement an abasic site within the hammerhead ribozyme, restoring cleavage activity [ 1 ] . Similarly, Porta and Lizardi engineered a hammerhead ribozyme that assumed an inactive secondary structure; upon the addition of an oligonucleotide that disrupted the engineered secondary structure, the ribozyme was activated [ 2 ] . More recently, it has previously been shown that many selected nucleic acid binding species (aptamers) undergo conformational changes upon ligand binding [ 3 4 5 6 ] In addition, when aptamers are conjoined to ribozymes, the ligand-induced conformational changes in the aptamers frequently modulate the structures and hence the activities of the ribozymes [ 7 8 9 ] For example, binding of theophylline to the anti-theophylline aptamer [ 10 ] modulates the conformation of residue [ 11 12 ] and the overall stability of the aptamer [ 10 13 ] . Appending the anti-theophylline aptamer to the hammerhead ribozyme allowed cleavage activity to be modulated by 110-fold by theophylline [ 13 ] . Similarly, appending the anti-theophylline aptamer to a small ribozyme ligase (L1) generated an aptazyme that was activated 1,600-fold by saturating theophylline concentrations [ 14 ] .
