It is … WebHowever, many questions regarding the catalytic mechanisms of ribozymes remain. This review compares the structures and possible catalytic mechanisms of four small self-cleaving RNAs: the hammerhead, hairpin, hepatitis delta virus, and in vitro–selected lead-dependent ribozymes. The organization of these small catalysts is contrasted to that ...
WebThe tRNA, Ul, and U6 transcripts were nuclear in localization and expressed at the highest levels, while the standard Pol II promoted transcripts were cytoplasmic and present at lower levels. The ability of these cassettes to confer ribozyme activity in vivo was tested with two assays. First, an SIV-growth hormone reporter gene was transiently ...
