Application

Micrococcal Nuclease can be used for the digestion of chromatin to identify the location of nucleosomes.
Nuclease micrococcal from Staphylococcus aureus has been used in a study to monitor hybridization reactions with DNA. It has also been used in a study to investigate the optimal conditions for assay of staphylococcal nuclease.

Biochem/physiol Actions

Hydrolyzes 5′-phosphodiester bonds of DNA.

The folding of staphylococcal nuclease (SNase) is known to proceed via a major intermediate in which the central OB subdomain is folded and the C-terminal helical subdomain is disordered. To identify the structural and energetic determinants of this folding free

Gene transcription can be regulated through alteration of chromatin structure, such as changes in nucleosome positioning and histone-modification patterns. Recent development of techniques based on the next-generation sequencing technology has allowed high-resolution analysis of genome-wide distribution of these chromatin features.

The time required to fold proteins usually increases significantly under conditions of high pressure. Taking advantage of this general property of proteins, we combined P-jump experiments with NMR spectroscopy to examine in detail the folding reaction of staphylococcal nuclease (SNase)
