Abstract

The sequence of reactions by which alginic acid is biosynthesized from sucrose in Azotobacter vinelandii was determined both by feeding radioactive individual enzymes involved. Results indicate that the first polymeric substance formed in the synthesis is polymannuronic acid and that mannuronic acid units are epimerized to guluronic acid at the polymer level. Guluronic acid does not appear to be formed at the monomer level, either free or in combination with GDP.

摘要

通过给参与其中的放射性单酶喂食，确定了棕色固氮菌中从蔗糖生物合成海藻酸的反应序列。结果表明，合成过程中形成的第一种聚合物质是聚甘露糖醛酸，并且甘露糖醛酸单元在聚合物水平上差向异构化为古洛糖醛酸。古洛糖醛酸似乎不是在单体水平上形成的，无论是游离形式还是与GDP结合的形式。
