The industrially important polymer, starch, is manufactured through a complex process involving multiple isoforms of several different enzymes. These contribute to alter the structure of starch which, in turn, affects its downstream industrial use. This review compares recent advances in our knowledge of starch metabolism in leaves and storage organs. Starch granule initiation and formation, enzyme complexes involved in starch metabolism and control of flux in starch synthesis and degradation are examined.
具有重要工业价值的聚合物淀粉,是通过一个涉及几种不同酶的多种同工型的复杂过程制造出来的。这些酶有助于改变淀粉的结构,而淀粉结构的改变反过来又会影响其下游的工业用途。本综述比较了我们在叶片和贮藏器官中淀粉代谢知识方面的最新进展。研究了淀粉颗粒的起始和形成、参与淀粉代谢的酶复合物以及淀粉合成和降解中的通量控制。
