Abstract
We develop a novel functional biosensor on a deoxyribozyme. A 5'-end-immobilized short Ca(2+)-dependent deoxyribozyme (dCGCTGGCAGGCTACAACGAGTCTTC) binds to a target RNA substrate (rGAAGACA decrease UGCCAGCG; decrease denotes an RNA cleavage site), and acts as an enzyme in the presence of Ca2+. It cleaves the target RNA substrate at one site of rAp decrease U in the asymmetric internal loop.
