Degrading nucleases
WebIn Arabidopsis, the SMALL RNA DEGRADING NUCLEASE (SDN) family of 30 to 50 exo-nucleases consisting of five family members degrades short RNAs in vitro and limits the accu-mulation of miRNAs in vivo [30]. Prior in vitro enzymatic assays with SDN1 were performed with free RNA oligonucleotides as substrates, and, in these assays, SDN1 … WebDouble stranded RNAs (dsRNA) degrading nuclease is responsible for the rapid degradation of dsRNA molecules, and thus accounts for variations in RNA interference (RNAi) efficacy among insect species.
