title: [Isolation and some properties of homogenous nuclease S1 from alpha-amyloryzin].
abstract: A purification method for isolating homogeneous single-strand specific nuclease S1 from alpha-amyloryzin has been developed. The yield was about 16% and purification factor--9000. Nuclease S1 thus obtained was proved to be free of contaminations of any others nucleolytic enzymes. It is shown for the first time that ribo- and deoxy-dinucleosidemonophosphates are hydrolyzed by nuclease S1 to form 5'-nucleotides with pH optimum for ApA equal to 4.6.
