摘要：

The arom multienzyme complex that catalyzes steps two through six in the prechorismate polyaromatic amino acid biosynthetic pathway has been purified up to 2000-fold from Euglena gracilis. The native arom aggregate has a molecular weight of approx. 249 000 based on a sedimentation coefficient of 9.5 and Stokes radius of 60 Å. A comparison between the arom aggregates of Neurospora crassa and Euglena gracilis and the possible phylogenetic relationships between the organisms are discussed. © 1979.
