RNase [T.sub.1] is an extracellular enzyme found by Sato and Egami in 1957 in Taka-Diastase, a commercial enzyme mixture from Aspergillus oryzae, and was shown to hydrolyze specifically the 3'-phosphodiester bond of guanylic acid
in RNA unlike the well-studied bovine pancreatic RNase A which is specific for the 3'-cytidylic and 3'-uridylic acids.
