additional information PhEst contains a catalytic triad formed by residues Ser147, Asp225 and His258. It shows no activity toward substrates with bulky acyl groups such as S-lactoylglutathione. Has a very narrow acyl-binding pocket in a typical alpha/beta-hydrolase fold Pseudoalteromonas haloplanktis ?
