If, in a clonal context, the fast-turnover leaves of a certain clonal plant species die back and join the soil as litter within the same brief season every year, while rhizomes or other plant parts form litter slowly but steadily throughout the year, then there might be an annual brief season of spatially regular, spot-wise nutrient enrichment.
Hence, the rapid turnover of residents in certain locations is a risk factor for bedbug infestation.
The recruitment of enolase by the RNA degradosome has been implicated in the turnover of certain transcripts, and it is mediated by a small segment of roughly a dozen residues that lie within a natively unstructured sub-domain of RNase E. Here, we present the crystal structure of enolase in complex with its recognition site from RNase E at 1.6 Å resolution.
Importantly, we demonstrated that proper turnover of certain key piRNA targets is essential for sperm formation.
Importantly, ectopic expression of piRNA-resistant forms of target genes in spermatids prevented the formation of sperms, suggesting that proper turnover of certain piRNA targets is essential for normal spermiogenesis.
Sequential turnover of certain cell cycle regulators, including cyclins and CKIs p21cip1/waf1 and p27kip1, are mediated by the 20S proteasome, which promotes proteolytic degradation through the ubiquitin/proteasome pathway.
The formation of isomerized aspartate (IsoAsp) within matrix proteins could also interfere with the normal turnover of cartilage as certain proteases, including matrix metalloproteinase-3 and some caspases, are unable to cleave their substrate if an IsoAsp is present in the target sequence [ 12].
