  Characterizing non-hydrolyzing Neisseria meningitidis serogroup A UDP-N-acetylglucosamine (UDP-GlcNAc) 2-epimerase using UDP-N-acetylmannosamine (UDP-ManNAc) and derivatives

  摘要：

  Neisseria meningitidis serogroup A non-hydrolyzing uridine 5'-diphosphate-N-acetylglucosamine (UDP-GlcNAc) 2-epimerase (NmSacA) catalyzes the interconversion between UDP-GlcNAc and uridine 5'-diphosphate-N-acetylmannosamine (UDP-ManNAc). It is a key enzyme involved in the biosynthesis of the capsular polysaccharide [-6ManNAc alpha 1-phosphate-](n) of N. meningitidis serogroup A, one of the six serogroups (A, B, C, W-135, X, and Y) that account for most cases of N. meningitidis-caused bacterial septicemia and meningitis. N. meningitidis serogroup A is responsible for large epidemics in the developing world, especially in Africa. Here we report that UDP-ManNAc could be used as a substrate for C-terminal His(6)-tagged recombinant NmSacA (NmSacA-His(6)) in the absence of UDP-GlcNAc. NmSacA-His(6) was activated by UDP-GlcNAc and inhibited by 2-acetamidoglucal and UDP. Substrate specificity study showed that NmSacA-His(6) could tolerate several chemoenzymatically synthesized UDP-ManNAc derivatives as substrates although its activity was much lower than non-modified UDP-ManNAc. Homology modeling and molecular docking revealed likely structural determinants of NmSacA substrate specificity. This is the first detailed study of N. meningitidis serogroup A UDP-GlcNAc 2-epimerase. (C) 2015 Elsevier Ltd. All rights reserved.

  Efficient one-pot multienzyme synthesis of UDP-sugars using a promiscuous UDP-sugar pyrophosphorylase from Bifidobacterium longum (BLUSP)

  摘要：

  从双歧杆菌（Bifidobacterium longum）ATCC55813株中克隆得到一种非特异的UDP-糖焦磷酸化酶（BLUSP），并将其与巴氏杆菌（Pasteurella multocida）的无机焦磷酸酶（PmPpA）有效配合使用，无论是否加入单糖1-激酶，都能实现UDP-半乳糖、UDP-葡萄糖、UDP-甘露糖及其衍生物的一锅法多酶合成。进一步对UDP-甘露糖衍生物进行化学修饰，形成了UDP-N-乙酰甘露糖胺。

  beta4GalTs, donor substrate specificity studies of two bacterial beta3GlcNAcTs from Helicobacter pylori (Hpbeta3GlcNAcT) and Neisseria meningitidis (NmLgtA), respectively, using a library of 39 sugar nucleotides were carried out. The two beta3GlcNAcTs have complementary donor substrate promiscuity and 13 different trisaccharides were produced. They were used to investigate the acceptor substrate specificities
