| Description | CpdB is a bacterial periplasmic protein with an N-terminal metallophosphatase domain and a C-terminal 3'-nucleotidase domain. This entry 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). |
