Acetyl esterase (aes) from Escherichia Coli

Acetyl esterase - This is a cytosolic hydrolase that can catalyze hydrlysis of esters of p-nitrophenyl derivatives

3D representation of the acetyl esterase from [http://www.rcsb.org/pdb/explore/explore.do?structureId=4KRX RCSB]

A form of this protein with added TEV and poly-HIS tags can be found here.

Usage and Biology

The hydrolase capacity of acetyl esterase makes it suitable for reporter application with substrates like acetylated xylan, ethyl acetate, cephalosporin C and derivatives[1] . Further it can be used for desacteylation of β-Lactam antibiotics[1] .


The acetyle esterase, apart from its hydrolase activity also binds competitively to malT, a transcription activator for the maltose operon, thus inhibiting regulation of genes required for maltose catabolism[2] [3].
