CA   Hydrolytically removes 5'-nucleotides successively from the 3'-hydroxy
CA   termini of 3'-hydroxy-terminated oligonucleotides.
CC   -!- Hydrolyzes both ribonucleotides and deoxyribonucleotides.
CC   -!- Has low activity toward polynucleotides.
CC   -!- A 3'-phosphate terminus on the substrate inhibits hydrolysis.
