岩藻依聚糖是来自海洋褐藻的基质多糖,由被硫酸酯基团取代的 α-L-岩藻糖主链组成,并被含有其他单糖残基的分支所掩蔽。尽管它们在许多同源和异源系统中作为生物活性化合物受到关注,但目前还没有具有岩藻多糖酶活性的方便来源可用于降解岩藻多糖。我们在此报告了能够降解各种褐藻岩藻依聚糖的细菌菌株的分离、表征和培养条件。这种细菌是黄杆菌科的一员,被证明可以分泌岩藻依聚糖内切水解酶活性。使用细胞外酶制剂来降解褐藻 Pelvetia canaliculata 中的岩藻依聚糖。最终产物包括由α-1→3-L-吡喃岩藻糖-2-硫酸盐-α-1→4-L-吡喃岩藻糖-2,3-二硫酸盐组成的二糖单元重复组成的四糖和六糖,其中3-连接的残基位于非还原端。
Fucoidans are matrix polysaccharides from marine brown algae, consisting of an α-l-fucose backbone substituted by sulfate-ester groups and masked with ramifications containing other monosaccharide residues. In spite of their interest as biologically active compounds in a number of homologous and heterologous systems, no convenient sources with fucanase activity are available yet for the degradation of the fucalean algae. We here report on the isolation, characterization, and culture conditions of a bacterial strain capable of degrading various brown algal fucoidans. This bacterium, a member of the family Flavobacteriaceae, was shown to secrete fucoidan endo-hydrolase activity. An extracellular enzyme preparation was used to degrade the fucoidan from the brown alga Pelvetia canaliculata. End products included a tetrasaccharide and a hexasaccharide made of the repetition of disaccharidic units consisting of α-1→3-l-fucopyranose-2-sulfate-α-1→4-l-fucopyranose-2,3-disulfate, with the 3-linked residues at the nonreducing end.
