Extracellular RNAase from Bac. amylozyma 9a has endonucleolytic character of the action on RNA, it splits in RNA 5'-phosphodiester bonds of GpXp type (where X is any nucleoside). The hydrolysis proceeds in two steps by the intramolecular transphosphorylation type of reaction to form guanosine-2',3'-phosphates and with the subsequent hydrolysis of cyclic bonds. The enzyme shows a preferable specificity to the single-stranded structure of the polyribonucleotides.
来自解淀粉芽孢杆菌9a的细胞外核糖核酸酶对RNA具有内切核酸酶活性，它能切割RNA中GpXp型（其中X为任何核苷）的5'-磷酸二酯键。水解通过分子内转磷酸化反应分两步进行，形成鸟苷-2',3'-磷酸，随后环状键发生水解。该酶对多聚核糖核苷酸的单链结构表现出优先特异性。
