Exonuclease-Endonuclease-Phosphatase (EEP) domain superfamily; This large superfamily includes the catalytic domain (exonuclease/endonuclease/phosphatase or EEP domain) of a diverse set of proteins including the ExoIII family of apurinic/apyrimidinic (AP) endonucleases, inositol polyphosphate 5-phosphatases (INPP5), neutral sphingomyelinases (nSMases), deadenylases (such as the vertebrate circadian-clock regulated nocturnin), bacterial cytolethal distending toxin B (CdtB), deoxyribonuclease 1 (DNase1), the endonuclease domain of the non-LTR retrotransposon LINE-1, and related domains. These diverse enzymes share a common catalytic mechanism of cleaving phosphodiester bonds; their substrates range from nucleic acids to phospholipids and perhaps proteins.

Streptococcus agalactiae RgfB, part of a putative two component signal transduction system, and related proteins; This family includes Streptococcus agalactiae RgfB (for regulator of fibrinogen binding) and related proteins. The function of RgfB is unknown. It is part of a putative two component signal transduction system designated rgfBDAC (the rgf locus was identified in a screen for mutants of Streptococcus agalactiae with altered binding to fibrinogen). RgfA,-C,and -D do not belong to this superfamily: rgfA encodes a putative response regulator, and rgfC, a putative histidine kinase. All four genes are co-transcribed, and may be involved in regulating expression of bacterial cell surface components. This family belongs to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds.

Neutral sphingomyelinases (nSMase) catalyze the hydrolysis of sphingomyelin in biological membranes to ceramide and phosphorylcholine; Sphingomyelinases (SMase) are phosphodiesterases that catalyze the hydrolysis of sphingomyelin to ceramide and phosphorylcholine. Eukaryotic SMases have been classified according to their pH optima and are known as acid SMase, alkaline SMase, and neutral SMase (nSMase). Eukaryotic proteins in this family are nSMases, and are activated by a variety of stress-inducing agents such as cytokines or UV radiation. Ceramides and other metabolic derivatives, including sphingosine, are lipid "second messenger" molecules that participate in the regulation of stress-induced cellular responses, including cell death, adhesion, differentiation, and proliferation. Bacterial neutral SMases, which also belong to this domain family, are secreted proteins that act as membrane-damaging virulence factors. They promote colonization of the host tissue. This family belongs to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds.

Phosphodiesterase domain of human TDP2, a 5'-tyrosyl DNA phosphodiesterase, and related domains; Human TDP2, also known as TTRAP (TRAF/TNFR-associated factors, and tumor necrosis factor receptor/TNFR-associated protein), is a 5'-tyrosyl DNA phosphodiesterase. It is required for the efficient repair of topoisomerase II-induced DNA double strand breaks. The topoisomerase is covalently linked by a phosphotyrosyl bond to the 5'-terminus of the break. TDP2 cleaves the DNA 5'-phosphodiester bond and restores 5'-phosphate termini, needed for subsequent DNA ligation, and hence repair of the break. TDP2 and 3'-tyrosyl DNA phosphodiesterase (TDP1) are complementary activities; together, they allow cells to remove trapped topoisomerase from both 3'- and 5'-DNA termini. TTRAP has been reported as being involved in apoptosis, embryonic development, and transcriptional regulation, and it may inhibit the activation of nuclear factor-kB. This family belongs to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds.
