DNAzyme description

 Reaction  Reacting groups  Substrates  Metal ion Linkage  Seq description
RNA cleavage Group 1 - 2'-OH

Group 2 - vicinal phosphate

S: cleavage in cis
M2+-independent
RNA phosphodiester N 40
 Buffer conditions
50 mM sodium cacodylate pH 7.5, 200 mM NaCl, 1 mM EDTA
 Catalytic region of the DNAzyme
TTACAGTCGTAGCGGTGGCATGCGTGCAGAGTAAGTGGGCG
Notes
DNAzymes are selected using 8-histaminyl-deoxyadenosine (dA<sup>im</sup>TP), 5-guanidinoallyl-deoxyuridine (dU<sup>ga</sup>TP), and 5-aminoallyl-deoxycytidine (dC<sup>aa</sup>TP) along with dGTP. The 17 nt all-RNA substrate is taken from the HIV-LTR untranslated message; the potential cleavage was directed at either of the four unpaired RNA linkages opposite the initial random region.
