Spleen exonuclease (EC 3.1.16.1, 3'-exonuclease, spleen phosphodiesterase, 3'-nucleotide phosphodiesterase, phosphodiesterase II) is an enzyme.[1] This enzyme catalyses the following chemical reaction
Exonucleolytic cleavage in the 5'- to 3'-direction to yield nucleoside 3'-phosphates (exonuclease type b)

This enzyme has a preference for single-stranded substrate.
PLD3 and/or PLD4 might be the genes encoding spleen exonuclease, as they have similar substrate specificity and tissue distribution.[2]
