Aplicación

Endoproteinase Glu-C from Staphylococcus aureus strain V8 is a serine protease used for selective cleavage of proteins for amino acid sequence determination or peptide mapping . Product P2922 has been used to linearize cyclic peptides in C. ternatea leaf extract.
Endoproteinase Glu-C from Staphylococcus aureus V8 has been used to digest reduced and alkylated cyclotides to produce linearized fragments.
It is used for selective cleavage of proteins for amino acid sequence determination or peptide mapping.

Acciones bioquímicas o fisiológicas

Staphylococcus strain V8 protease specifically cleaves peptide bonds on the carboxyl side of aspartic and glutamic acid residues when used in phosphate buffer. When used in ammonium bicarbonate buffer or ammonium acetate buffer cleavage is restricted to the carboxyl side of glutamic acid residues only. The enzyme exhibits maximal activity from pH 4.0 to 7.8. If hemoglobin is used as the substrate, maximal activity is at pH 4.0. The maximal activity is at pH of 7.8 when casein is the substrate.

Definición de unidad

One unit will hydrolyze 1 μmole of N-t-Boc-L-glutamic acid α-phenyl ester per min at pH 7.8 at 37 °C. One unit is equivalent to ~0.004 casein digestion unit.

Common yet often overlooked, deamidation of peptidyl asparagine (Asn or N) generates aspartic acid (Asp or D) or isoaspartic acid (isoAsp or isoD). Being a spontaneous, non-enzymatic protein post-translational modification, deamidation artifact can be easily introduced during sample preparation, especially
