| phosphodiester hydrolases | Enzymes (EC sub-subclass 3.1.4) cleaving phosphodiester bonds, such as those in cAMP or between nucleotides in nucleic acids, liberating smaller poly-or oligonucleotide units or mononucleotides but not inorganic phosphate. Synonym: phosphodiester hydrolases. (05 Mar 2000) |

| phosphodiester bond | <chemistry> Not a precise term. Refers to any molecule in which two parts are joined through a phosphate group. Examples are found in RNA, DNA, phospholipids, cyclic nucleotides, nucleotide diphosphates and triphosphates. (18 Nov 1997) |
| phosphodiester linkage | <biochemistry> A chemical linkage in which two alcohols are esterically boundto a bridging molecule of phosphoric acid. (31 Dec 1997) |
| acid anhydride hydrolases | <enzyme> A group of enzymes that catalyze the hydrolysis of diphosphate bonds in compounds such as nucleoside di- and tri-phosphates, and sulfonyl-containing anhydrides such as adenylylsulfate. (enzyme nomenclature, 1992). Registry number: EC 3.6 (12 Dec 1998) |
| alpha-aminoacyl-peptide hydrolases | <enzyme> Registry number: EC 3.4.11. (12 Dec 1998) |
