Abstract
Bacterial ribonuclease III (RNase III) belongs to the RNase III enzyme family, which plays a pivotal role in controlling mRNA stability and RNA processing in both prokaryotes and eukaryotes. In the Vibrio vulnificus genome, one open reading frame encodes a protein homologous to E. coli RNase III, designated Vv-RNase III, which has 77.9 % amino acid identity to E. coli RNase III. Here, we report that Vv-RNase III has the same cleavage specificity as E. coli RNase III in vivo and in vitro. Expressing Vv-RNase III in E. coli cells deleted for the RNase III gene (rnc) restored normal rRNA processing and, consequently, growth rates of these cells comparable to wild-type cells. In vitro cleavage assays further showed that Vv-RNase III has the same cleavage activity and specificity as E. coli RNase III on RNase III-targeted sequences of corA and mltD mRNA. Our findings suggest that RNase III-like proteins have conserved cleavage specificity across bacterial species.
