Example sentences for: ribozyme

How can you use “ribozyme” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • The M6P/IGF2R ribozyme we constructed has 13-bp binding arms complementary to the target site of M6P/IGF2R mRNA, and a catalytic core (Fig.

  • 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 ] .

  • We also examined the effect of the ribozyme on the M6P-binding activity of the M6P/IGF2R using the M6P-bearing lysosomal enzyme, β-glucuronidase, as a probe.

  • We examined the effects of ribozyme expression on apoptosis of cultured MCF-7 cells.

  • Sirna began as the biotech startup Ribozyme Pharmaceuticals, which tried to develop ribozymes to treat several conditions, including hepatitis C. A ribozyme is an RNA molecule whose sequence and structure allow it to cleave specific target RNA molecules (see Figure 1).
