Abstract

X-ray diffraction studies to 2.8-A resolution have yielded the three-dimensional structure of mitochondrial aspartate aminotransferase (L-aspartate:2-oxoglutarate aminotransferase, EC 2.6.1.1), an isologous alpha 2 dimer (Mr = 2 x 45,000). The subunits are rich in secondary structure and contain two domains, one of which anchors the coenzyme, pyridoxal 5'-phosphate. Each active site lies between the subunits and is composed of residues from both of them.

摘要

对线粒体天冬氨酸氨基转移酶(L-天冬氨酸:2-氧代戊二酸氨基转移酶,EC 2.6.1.1)进行的分辨率达2.8埃的X射线衍射研究,得出了其三维结构,该酶是一种同源α2二聚体(Mr = 2×45,000)。亚基富含二级结构,包含两个结构域,其中一个结构域固定辅酶磷酸吡哆醛。每个活性位点位于两个亚基之间,由两个亚基的残基组成。
