摘　　要：腺苷5'-磷酰硫酸激酶(APSK)催化APS磷酸化生成3'-磷酸-腺苷5'-磷酰硫酸(PAPS),PAPS进一步作为硫酸根供体参与胞内的硫酸化反应。因此,在这些生物体中,APS激酶是硫酸盐同化的重要组成部分。介绍APS激酶的结构、功能、作用机制,综述植物APS激酶当前的研究进展。Adenosine5′-phosphoryl sulfate kinase catalyzes the phosphorylation of APS to produce3′-phosphate-adenosine5′-phosphoryl sulfuric acid,and PAPS is further used as a sulfate donor in the intracellular sulfation reaction.Thus,in these organisms,APS kinase is an important component of sulfate assimilation.The structure,function,mechanism and function of APS kinase were introduced.The current research progress of APS kinase was reviewed.
