일반 설명
Sialic acid aldolases, or N-acetylneuraminate lyases, catalyze the reversible aldol cleavage of N-acetylneuraminic acid to form pyruvate and N-acetyl-D-mannosamine. In nature, N-acetylneuraminate lyase mainly occurs in pathogens.
애플리케이션
Sialic acid aldolase can be used to synthesize unnatural sugars of C(6) to C(10) for the design of antagonists and inhibitors of glycoenzymes.
단위 정의
One unit will catalyze the formation of 1.0 μmol Neu-5-Ac from Man-N-Ac and pyruvate per minute at 37°C at pH 8.0.
물리적 형태
Lyophilized powder containing Tris-HCl and NaCl
분석 메모
Enzymatic activity assays are performed in Tris-HCl buffer (100 mM, pH 7.5) containing Neu-5-Ac (10 mM) at 37 °C for 15 min and analyzed using capillary electrophoresis with UV detection at 200 nm.

N-Acetylneuraminate lyases (NALs) or sialic acid aldolases catalyze the reversible aldol cleavage of N-acetylneuraminic acid (Neu5Ac) to form pyruvate and N-acetyl-d-mannosamine (ManNAc). In nature, N-acetylneuraminate lyase occurs mainly in pathogens. However, this paper describes how an N-acetylneuraminate lyase was cloned

In a recent directed-evolution study, Escherichia coli D-sialic acid aldolase was converted by introducing eight point mutations into a new enzyme with relaxed specificity, denoted RS-aldolase (also known formerly as L-3-deoxy-manno-2-octulosonic acid (L-KDO) aldolase), which showed a preferred selectivity toward

Active inclusion bodies of polyphosphate kinase 3 and cytidine 5'-monophosphate kinase were combined with whole cells that co-express sialic acid aldolase and CMP-sialic acid synthetase. The biocatalytic mixture was used for the synthesis of CMP-sialic acid, which was then converted
