Family: Carb_B_Platyhelminthe

Block: C

Parent Family: Carboxylesterase


These proteins have a cytoplasmic domain and a transmembrane domain N-terminal similar to neurotactine. Carboxylesterase type B (CestB) increased expression in flukes exposed to triclabendazole (TCBZ). Three mutations in TCBZ-resistant parasites allow binding of TCBZ-SX. TCBZ is metabolized into TCBZSO by the host liver but also by the parasites. This enzyme hydrolyses p-nitrophenyl acetate. Other Platyhelmithe CO esterase belong to neurotactin, gliotactin, neuroligin Cholinesterase or OtherNon-catalytic_C families
