What is Identification of some soluble esterases of the carrot (Daucus carota L.) about?
Aqueous-extractable esterases of the carrot (DUUCILS curofa L.) showed optimal activity between pH 6.8 and 7.2. Acetyl, propionyl, and n-butyryl esters of phenol, sodium 2-naphthol-6-sulfonate, and glycerol and n-hexyl ester of sodium 2-naphthol-6-sulfonate were hydrolyzed by carrot esterases. Lack of activity with n-octyl ester of sodium 2-naphthol-6-sulfonate and triolein indicated the absence of a lipase or an esterase able to hydrolyze long-chain soluble esters. Esterases capable of hydrolyzing acetyl-, propionyl-, and n-butyrylcholine also were absent in the carrot extract. Carrot esterases showed maximal activity with phenyl esters, while the esters of sodium 2-naphthol-6-sulfonate and triglycerides were hydrolyzed at slower rates. Activity decreased as the acyl chain-length was increased. Inhibition studies with diethylp-nitrophenyl thiophosphate (parathion), tetraethyl pyrophosphate (TEPP) and diisopropylphosphorofluoridate (DFP) at concentrations from 10-l to lo-10 M with nine substrates indicated the presence of six esterases. Four esterases were classified as carboxylesterases (EC 3.1.1.1) and two fit into the arylesterase (EC 3.1.1.2) classification. Evidence is present
