• 論文の詳細を見る

• A commercial preparation of glucoamylase from Aspergllus niger consisted of least six species (A-II〜IV and B-I〜III), five forms of which were fully characterized. They were apparently different in molecular weight, sedimentation constant(s_<20, w>), isoelectric point (pI), chemical composition, kinetic parameters (K_0, molecular activity ; k_<int>, intrinsic rate constant), and other enzymatic properties. When compared with enzymological characteristics as well as serological ones, B-I was found to be a peculiar enzyme among them. Furthermore, A-II was significantly discriminated from the other enzymes in respect of molecular weight and composition of amino acid, suggesting that A-II might be the product of transcription of a different DNA site.
