Protein Domain : IPR019819

Name  Carboxylesterase type B, conserved site Short Name  Carboxylesterase_B_CS
Type  Conserved_site Description  Higher eukaryotes have many distinct esterases. Among the different types arethose which act on carboxylic esters (). Carboxyl-esterases havebeen classified into three categories (A, B and C) on the basis ofdifferential patterns of inhibition by organophosphates. The sequence of anumber of type-B carboxylesterases indicates [, , ]that the majority are evolutionary related. As is the case for lipases and serine proteases, the catalytic apparatus ofesterases involves three residues (catalytic triad): a serine, a glutamate oraspartate and a histidine.As is the case for lipases and serine proteases, the catalytic apparatus of esterases involves three residues (catalytic triad): a serine, a glutamate or aspartate and a histidine. This entry represents a well conserved site located in the N-terminal section, which contains a cysteine involved in a disulphide bond. Human esterase-D, also a type-B carboxylesterase, does not seem to be evolutionary related.
