Description

Application

Ribonuclease B from bovine pancreas is used in the digestion of RNA during cell cycle platform analysis.

Biochem/physiol Actions

Native RNase BS generated by subtilisin digestion of native RNase B comprising of amino acid residues 21-124 of RNase B, is sensitive to PNGase F digestion. Intramolecular N-glycans of bovine pancreatic RNase B function like chaperone. RNase B is found to be much faster than RNase A, while RNase A is liable to aggregate during regeneration. The stimulatory effect of Asn-oligosaccharide (which corresponds to the most predominant sugar chain of RNase B) reveals that the N-glycans of RNase B facilitates the transformation of bulky intermediates into folded, compact species.

Rapid Glycan Prep & Analysis by LC-MS Workflow

PNGase Fast denaturing buffer and enzyme provide results similar to a conventional 20-hour protocol, reducing workflow time to about 1 hour.

The structural basis of the difference in sensitivity for PNGase F in the de-N-glycosylation of the native bovine pancreatic ribonucleases B and BS.

In glycoanalysis protocols, N-glycans from glycoproteins are most frequently released with peptide- N (4)-( N-acetyl-beta-glucosaminyl)asparagine amidase F (PNGase F). As the enzyme is an amidase, it cleaves the NH-CO linkage between the Asn side chain and the Asn-bound GlcNAc residue.

A chaperone-like function of intramolecular high-mannose chains in the oxidative refolding of bovine pancreatic RNase B.

This paper describes a chaperone-like function of the intramolecular N-glycans of bovine pancreatic RNase B. We studied air-oxidative regeneration from reductively denatured species of RNase B and its nonglycosylated form, RNase A. RNase B was reactivated much faster than RNase

Glycosylation States on Intact Proteins Determined by NMR Spectroscopy.

Audra A Hargett et al.

Molecules (Basel, Switzerland), 26(14) (2021-07-25)

Protein glycosylation is important in many organisms for proper protein folding, signaling, cell adhesion, protein-protein interactions, and immune responses. Thus, effectively determining the extent of glycosylation in glycoprotein therapeutics is crucial. Up to now, characterizing protein glycosylation has been carried
