2',3'-cyclic-nucleotide 2'-phosphodiesterase; 2',3'-cyclic-nucleotide 2'-phosphodiesterase is a bifunctional enzyme localized to the periplasm of Gram-negative bacteria. 2',3'-cyclic-nucleotide 2'-phosphodiesters are intermediates formed during the hydrolysis of RNA by the ribonuclease I, which is also found to the periplasm, and other enzymes of the RNAse T2 family. Bacteria are unable to transport 2',3'-cyclic-nucleotides into the cytoplasm. 2',3'-cyclic-nucleotide 2'-phosphodiesterase contains 2 active sites which catalyze the reactions that convert the 2',3'-cyclic-nucleotide into a 3'-nucleotide, which is then converted into nucleic acid and phosphate. Both final products can be transported into the cytoplasm. Thus, it has been suggested that 2',3'-cyclic-nucleotide 2'-phosphodiesterase has a 'scavenging' function. Experimental evidence indicates that 2',3'-cyclic-nucleotide 2'-phosphodiesterase enables Yersinia enterocolitica O:8 to grow on 2'3'-cAMP as a sole source of carbon and energy ().

Escherichia coli CpdB and related proteins, N-terminal metallophosphatase domain; CpdB is a bacterial periplasmic protein with an N-terminal metallophosphatase domain and a C-terminal 3'-nucleotidase domain. This alignment model represents the N-terminal metallophosphatase domain, which has 2',3'-cyclic phosphodiesterase activity, hydrolyzing the 2',3'-cyclic phosphates of adenosine, guanosine, cytosine and uridine to yield nucleoside and phosphate. CpdB also hydrolyzes the chromogenic substrates p-nitrophenyl phosphate (PNPP), bis(PNPP) and p-nitrophenyl phosphorylcholine (NPPC). CpdB is thought to play a scavenging role during RNA hydrolysis by converting the non-transportable nucleotides produced by RNaseI to nucleosides which can easily enter a cell for use as a carbon source. This family also includes YfkN, a Bacillus subtilis nucleotide phosphoesterase with two copies of each of the metallophosphatase and 3'-nucleotidase domains. The N-terminal metallophosphatase domain belongs to a large superfamily of distantly related metallophosphatases (MPPs) that includes: Mre11/SbcD-like exonucleases, Dbr1-like RNA lariat debranching enzymes, YfcE-like phosphodiesterases, purple acid phosphatases (PAPs), YbbF-like UDP-2,3-diacylglucosamine hydrolases, and acid sphingomyelinases (ASMases). MPPs are functionally diverse, but all share a conserved domain with an active site consisting of two metal ions (usually manganese, iron, or zinc) coordinated with octahedral geometry by a cage of histidine, aspartate, and asparagine residues. The conserved domain is a double beta-sheet sandwich with a di-metal active site made up of residues located at the C-terminal side of the sheets. This domain is thought to allow for productive metal coordination.

Thermus thermophilus SoxB and related proteins, N-terminal metallophosphatase domain; SoxB (sulfur oxidation protein B) is a periplasmic thiosulfohydrolase and an essential component of the sulfur oxidation pathway in archaea and bacteria. SoxB has a dinuclear manganese cluster and is thought to catalyze the release of sulfate from a protein-bound cysteine S-thiosulfonate. SoxB is expressed from the sox (sulfur oxidation) gene cluster, which encodes 15 other sox genes, and has two domains, an N-terminal metallophosphatase domain and a C-terminal 5'-nucleotidase domain.

pullulanase, extracellular, Gram-positive; Pullulan is an unusual, industrially important polysaccharide in which short alpha-1,4 chains (maltotriose) are connected in alpha-1,6 linkages. Enzymes that cleave alpha-1,6 linkages in pullulan and release maltotriose are called pullulanases although pullulan itself may not be the natural substrate. In contrast, a glycogen debranching enzyme such GlgX, homologous to this family, can release glucose at alpha,1-6 linkages from glycogen first subjected to limit degradation by phosphorylase. Characterized members of this family include a surface-located pullulanase from Streptococcus pneumoniae () and an extracellular bifunctional amylase/pullulanase with C-terminal pullulanase activity (.

LPXTG-motif cell wall anchor domain; This model describes the LPXTG motif-containing region found at the C-terminus of many surface proteins of Streptococcus and Streptomyces species. Cleavage between the Thr and Gly by sortase or a related enzyme leads to covalent anchoring at the new C-terminal Thr to the cell wall. Hits that do not lie at the C-terminus or are not found in Gram-positive bacteria are probably false-positive. A common feature of this proteins containing this domain appears to be a high proportion of charged and zwitterionic residues immediatedly upstream of the LPXTG motif. This model differs from other descriptions of the LPXTG region by including a portion of that upstream charged region. [Cell envelope, Other]
