S1 nuclease

a single-strand-specific endonuclease that degrades DNA and RNA to nucleoside 5′-monophosphates. The enzyme is a single polypeptide chain of molecular weight 32,000 and is isolated from 'takadiesterase', a digestive enzyme preparation from Aspergillus oryzae. Widely used in molecular biology to map the position of mRNA to its DNA, and also used to remove single-stranded tails from DNA fragments, to produce blunt ends to open up hairpin-loop structures.
