α(2→3,6,8,9) Neuraminidase from Streptococcus pneumoniae, Recombinant

inquiry

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 Weight

~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

Buffer

5X concentrated buffer which when diluted gives 50 mM sodium phosphate pH 6.0.

Synonyms

neuraminidase; sialidase; α-neuraminidase; acetylneuraminidase; exo-α-sialidase
