putative serine hydrolase

nonane-4,6-dione + H2O = pentan-2-one + butanoate
reaction mechanism, the reaction catalyzed by OPH is typical of alpha/beta-hydrolases, except that the cleaved bond is between two carbon atoms. Here electron delocalization seems to play an essential role. Upon C-C bond breaking, the negative charge on CO1' is probably stabilized by hydrogen bonds to the backbone NH of Ser66 and Val67, thus forming a second oxyanion hole. This anion-binding beta3-alpha1 loop might promote spontaneous oxidation of Cys172 to a sulfonate
