Descripción general

The Nuclease S1 enzyme from Aspergillus oryzae has the ability to degrade single-stranded oligonucleotides composed of either deoxynucleotides or ribonucleotides.

Aplicación

Nuclease S1 from Aspergillus oryzae has been used in a study to assess a biochemical method for mapping mutational alterations in DNA. It has also been used in a study to investigate the DNA damage and repair in a γ-irradiated rat brain tumor.

Acciones bioquímicas o fisiológicas

SI nuclease from Aspergillus oryzae can generate double-stranded DNA breaks in response to DNA nicks or abasic sites.
Nuclease S1 isolated from Aspergillus oryzae exhibits endo- and exolytic hydrolytic activity for the phosphodiester bonds of single-stranded DNA and RNA yielding 5′-phosphomononucleotide and 5′-phosphooligonucleotide end-products. It is used to digest non-annealed polynucleotide tails and hairpin loops in RNA and DNA duplexes and can be used to convert superhelical DNA to the linear form.

Definición de unidad

S(1) nuclease, the single-strand specific nuclease from Aspergillus oryzae can cleave both strands of circular covalently closed, superhelical simian virus 40 (SV40) DNA to generate unit length linear duplex molecules with intact single strands. But circular, covalently closed, nonsuperhelical DNA

Nuclease S1 specifically hydrolizes tRNAs in their anticodon loops, forming new 5' phosphate and 3' OH ends. Some single-stranded regions are not cut by nuclease S1. The strong preference of nuclease S1 for the anticodon region can be used for

The hyperthermophilic Sulfolobus islandicus rod-shaped virus 2 (SIRV2) encodes a 25-kDa protein (SIRV2gp19) annotated as a hypothetical protein with sequence homology to the RecB nuclease superfamily. Even though SIRV2gp19 homologs are conserved throughout the rudivirus family and presumably play a

We demonstrate that S1 nuclease converts supercoiled plasmid DNA to unit-length, linear dsDNA through the creation of a single, double-stranded break in a plasmid molecule. These double-stranded breaks occur not only in the origin of replication near inverted repeats but
