SYNONYMS
N-acetylneuraminate lyase, N-acetylneuraminate pyruvate-lyase, N-acetylneuraminic acid aldolase, NALase, Sialate lyase, Sialic acid aldolase, Sialic acid lyase, nanA, npl, b3225, JW3194.INTRODUCTION
N-acetylneuraminate lyase (NanA) is a member of a family of lyases, specifically the oxo-acid-lyases, which cleave carbon-carbon bonds. NanA catalyzes the cleavage of N-acetylneuraminic acid (sialic acid) to form pyruvate and N-acetyl-D-mannosamine. NanA is inhibited by reduction with NaBH4 in the presence of the substrate, which indicates that it belongs to the Schiff-base-forming Class I aldolases. NanA is strongly inhibited by Cu2+ ions, p-chloromercuribenzoate and N-bromosuccinimide, it is also inhibited competitively by the reaction product, pyruvate, and its structurally related compounds, dihydroxyacetone and DL-glyceraldehyde.DESCRIPTION
NANA produced in E.Coli is a single, non-glycosylated polypeptide chain containing 317 amino acids (1-297 a.a.) and having a molecular mass of 34.7kDa.NANA is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

E.coli genomic library construct 求教
最近我在做一个E.coli genomic library construct，遇到一些问题，向论坛上的大侠请教。请帮忙看看问题出在哪里。万分感谢！ 我的方法流程如下： 1。用SDS和蛋白酶K提取E.coli genomic DNA (用的是E.coli的一个突变菌株) 2。insert: Sau3AI digest E.coli genomic DNA, partail digestion, to get 2kb-5kb, 这一步我摸过酶切时间梯度，用0.1unit Sau3AI
