Descrizione generale

Endonuclease from Serratia marcescens is a dimer containing two identical monomeric units with distinct protein folds. The core contains a six-stranded antiparallel β-sheet flanked by α-helices on either side. Each monomer bears one active site. This enzyme is a magnesium-dependent nucleases.

Applicazioni

Turbonuclease from Serratia marcescens has been used for cell lysis during proximity biotinylation assay (BioID) and affinity-purification. It has also been used as a component of lysis buffer for protein extraction from cell lines for affinity purification studies.
Turbonuclease has been used in a study to assess the TY3 gag3 spacer effect on intracellular condensation and uncoating.
Utilizzato per rimuovere gli acidi nucleici dai campioni di proteine.

Azioni biochim/fisiol

Endonuclease from Serratia marcescens is effective against both single- and double-stranded DNA and RNA. It mediates the digestion of the 3′ O—P bond resulting in oligonucleotides ending with 5′ monophosphate. The activity of this enzyme is known to be less affected by the reducing and chaotropic agents. It is highly stable at room temperature. This endonuclease eliminates the undesired nucleic acids in downstream processing.
Turbonuclease provides a nuclease treatment by reducing viscosity and degrading RNA, genomic DNA, baculovirus DNA, and unencapsidated vector DNA.
Digerisce DNA ed RNA nativi o denaturati con calore.

Definizione di unità

One unit will digest sonicated salmon sperm DNA to acid-soluble oligonucleotides equivalent to a ΔA260 of 1.0 in 30 min at pH 8.0 at 37 °C.

The Omicron lineage of SARS-CoV-2, which was first described in November 2021, spread rapidly to become globally dominant and has split into a number of sublineages. BA.1 dominated the initial wave but has been replaced by BA.2 in many countries.
