Phosphodiesterase YfcE

UniProtKB accession:  P67095

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Shows phosphodiesterase activity (PubMed:15808744, PubMed:17586769, PubMed:18757371). Shows significant activity toward bis-p-nitrophenyl phosphate (bis-pNPP), an artificial substrate commonly used to detect phosphodiesterase activity (PubMed:15808744, PubMed:17586769, PubMed:18757371). Also hydrolyzes, with lower efficiency, two other artificial phosphodiesterase substrates, thymidine 5'-monophosphate p-nitrophenyl ester (pNP-TMP) and p-nitrophenylphosphorylcholine (pNPPC) (PubMed:15808744, PubMed:17586769). Shows phosphomonoesterase activity toward p-nitrophenyl phosphate (pNPP), with much lower catalytic efficiency (PubMed:18757371). No activity was detected against a wide variety of naturally occurring phosphomonoesters and phosphodiesters, including various 2',3'- and 3',5'-cyclic nucleotides, suggesting that YfcE is highly specific for its physiological substrate, which is not yet known (PubMed:17586769).
