半岛bd体育手机客户端 说明
一般描述
Cytidine monophosphate (CMP)-Sialic Acid Synthetase fromNeisseria meningitidisgroup B is encoded in neuA gene. The protein has a molecular weight of 24.8 kDa.
应用
The enzyme has been utilized to synthesize CMP-sialic acid and its derivatives.
生化/生理作用
Cytidine monophosphate (CMP)-sialic acid synthetase catalyses the conversion ofN?acetylneuraminic acid (NeuNAc) to CMP-NeuNAc. CMP-sialic acid synthetase has globular α/β domain and is categorised under αβα three-layered sandwich fold. The dimerization domain aids the interaction between the monomers. It also has mononucleotide binding and NeuAc binding pocket. Mg2+is essential for the catalytic functionality of CMP-sialic acid synthetase.
单位定义
One unit will catalyze the formation of 1 μmol CMP-Neu-5-Ac from Neu-5-Ac and CTP per minute at 37 ℃ at pH 8.0.
外形
Supplied as a lyophilized powder containing Tris-HCl and NaCl.
分析说明
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 ℃ for 30 min and analyzed using capillary electrophoresis with a UV detector (200 nm).
