CMP-Sialic Acid Synthetase from Neisseria meningitidis group B

recombinant, expressed in E. coli BL21, ≥10 units/mg protein

Synonym: CTP: N-Acylneuraminate cytidylyltransferase

Description

Analysis Note

Enzymatic activity assays are performed in Tris-HCl buffer (100 mM, pH 8.5) containing Neu-5-Ac (1 mM) and CTP (1 mM) at 37 °C for 30 min and analyzed using capillary electrophoresis with a UV detector (200 nm).

Unit Definition

One unit will catalyze the formation of 1 μmol CMP-Neu-5-Ac from Neu-5-Ac and CTP per minute at 37 °C at pH 8.0.

Physical form

Supplied as a lyophilized powder containing Tris-HCl and NaCl.

Application

The enzyme has been utilized to synthesize CMP-sialic acid and its derivatives.1
