  • Synthesis of 3-deoxy-D-manno-2-octulosonic acid (KDO) and its analogs based on KDO aldolase-catalyzed reactions
    作者:Takeshi Sugai、Gwo Jenn Shen、Yoshitaka Ichikawa、Chi Huey Wong
    DOI:10.1021/ja00055a008
    日期:1993.1
    3-Deoxy-D-manno-2-octulosonic acid (D-KDO) was synthesized from D-arabinose and pyruvate in 67% yield by using KDO aldolase (EC 4.1.2.21) from Aureobacterium barkerei strain KDO-37-2 (ATCC 49977). Studies on the substrate specificity of the enzyme with more than 20 natural and unnatural sugars indicate that this enzyme widely accepts trioses, tetroses, pentoses, and hexoses as substrates, especially

    Aureobacterium barkerei strain KDO-37-2 (ATCC 49977) KDO aldolase (EC 4.1.2.23) isolated therefrom are disclosed. The DKDO aldolase is further disclosed to have a broad substrate specificity with respect to its reverse reaction, i.e. the condensation of aldoses with pyruvate to form a wide range of 2-keto-3-deoxy-onic acids, including 2-keto-3-deoxy-nonulosonic acid, 2-keto-3-deoxy-octulosonic acid, 2-keto-3-deoxy-heptulosonic acid, and 2-keto-3-deoxy-hexulosonic acid. In particular, 3-deoxy-D-manno-2-octulosonic acid (D-KDO), a vital component of lipopolysaccharides found in the bacterial outer membrane may be synthesized from D-arabinose and pyruvate in 67% yield. Additionally, protected forms of the KDO aldolase products, e.g. hexaacetyl 2-keto-3-deoxy-nonulosonic acid and pentaacetyl 2-keto-3-deoxy-octulosonic acid, may be decarboxylated to form the corresponding 2-deoxy-aldoses, e.g. 2-deoxy-octulose and 2-deoxy-heptulose respectively.

    2-Ketoaldonic acid is synthesized by aldolase condensation reaction involving pyruvate and an aldose acceptor in the presence of excess pyruvate. After the reaction is substantially complete, the excess pyruvate is removed from the reaction mixture by treatment with pyruvate decarboxylase.
