摘要
A complex formation between hemin and a congruous oligonucleotide not only greatly enhances the former's peroxidative activity but also results in a biocatalyst (DNAzyme) with a novel specificity. Herein substrate, regio-, enantiomeric, and diastereomeric selectivities of heme, the DNAzyme, and the enzyme horseradish peroxidase are comparatively examined.
