Nuclease S7 has been used in ribonuclease selection process for ribosome profiling.

Biochem/physiol Actions

Nuclease S7 is an endonuclease that mainly cleaves single-stranded substrates. It also cleaves double-stranded DNA or RNA. It cleaves the 5′-phosphodiester bonds of RNA and DNA to yield 3′-mononucleotides and oligonucleotides. Activity of the enzyme is dependent on Ca2+ and can be completely inactivated by the addition of EDTA. Nuclease S7 cleavage is highly specific to AT rich region than GC on the DNA.

Unit Definition

One unit releases a sufficient amount of acid-soluble oligonucleotides to produce an increase of 1.0 at A260.

Storage and Stability

Store unopened reagent at 2-8 °C; when diluted to 1 mg/mL, store at -15 to -25 °C.

Chloroplast genomes encode ∼ 37 proteins that integrate into the thylakoid membrane. The mechanisms that target these proteins to the membrane are largely unexplored. We used ribosome profiling to provide a comprehensive, high-resolution map of ribosome positions on chloroplast mRNAs

In mammalian spermatozoa, most but not all of the genome is densely packaged by protamines. Here we reveal the molecular logic underlying the retention of nucleosomes in mouse spermatozoa, which contain only 1% residual histones. We observe high enrichment throughout

There has been a surge of interest towards targeting protein synthesis to treat diseases and extend lifespan. Despite the progress, few options are available to assess translation in live animals, as their complexity limits the repertoire of experimental tools to

In order to produce proteins essential for their propagation, many pathogenic human viruses, including SARS-CoV-2 the causative agent of COVID-19 respiratory disease, commandeer host biosynthetic machineries and mechanisms. Three major structural proteins, the spike, envelope and membrane proteins, are amongst
