- Аннотация: The interaction of MvaI restriction endonuclease with 14-membered deoxyribonucleotide duplexes containing modifications within the recognition site (CCA/TGG) has been studied. Substitution of m5dC for the internal dC residue, as well as substitution of fl5dU or rU for dT did not influence the initial rate of hydrolysis (vo) of modified strands, whereas the hydrolysis of unmodified strands was inhibited in some cases. Furthermore, the substitution of a pyrophosphate bond for a scissile phosphodiester bond in one strand completely inhibited digestion in this strand without any decrease of the rate of hydrolysis of the unmodified strand. In contrast to EcoRII endonuclease, which recognizes the same DNA sequence, in the case of MvaI endonuclease substrate recognition is possible in a wide range of conformational, electronic and hydrophobic alterations within the recognition site.
