Cat No.
NATE-0971
Description
Neuraminidase, releases α(2-3)-linked sialic acid from oligosaccharides, glycoproteins, complex carbohydrates.
Abbr
α-Neuraminidase, Recombinant (Streptococcus pneumoniae)
Alias
Sialidase
Source
E. coli
Species
Streptococcus pneumoniae
Form
Lyophilized from 20 mM Tris-HCl, 25 mM NaCl (pH 7.5)
Molecular Mass
~75 kD
Specificity
This enzyme releases α(2-3)-linked N-acetylneuraminic acid (Neu5Ac, NANA) from complex carbohydrates. Sialidase is also active against N-glycoylneuraminic acid1 (Neu5Gc, NGNA), although similarly to other sialidases2 the activity is lower toward Neu5Gc than Neu5Ac.
Unit Definition
One unit is defined as the amount of enzyme required to catalyze the release of 1 μmole of p-nitrophenol from p-nitrophenyl-α-D-N-acetylneuraminic acid per minute at 37° C, pH 5.5.
Optimum pH
5.5
Synonyms
neuraminidase; sialidase; α-neuraminidase; acetylneuraminidase; exo-α-sialidase
