Carboxylesterase family
Encyclopedia
Carboxylesterase, type B is a family of evolutionarily related proteins
.
Higher eukaryotes have many distinct esterase
s. Among the different types are those which act on carboxylic esters . Carboxyl-esterases have been classified into three categories (A, B and C) on the basis of differential patterns of inhibition by organophosphates. The sequence of a number of type-B carboxylesterases indicates that the majority are evolutionarily related. 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 family belongs to the superfamily of proteins with the Alpha/beta hydrolase fold

Protein family
A protein family is a group of evolutionarily-related proteins, and is often nearly synonymous with gene family. The term protein family should not be confused with family as it is used in taxonomy....

Esterase
An esterase is a hydrolase enzyme that splits esters into an acid and an alcohol in a chemical reaction with water called hydrolysis.A wide range of different esterases exist that differ in their substrate specificity, their protein structure, and their biological function.- EC classification/list...

Alpha/beta hydrolase fold
In molecular biology, the alpha/beta hydrolase fold is common to a number of hydrolytic enzymes of widely differing phylogenetic origin and catalytic function. The core of each enzyme is an alpha/beta-sheet , containing 8 strands connected byhelices...
