Abstract:
Indolyl and nitrophenyl 5-O-hydroxycinnamoyl-alpha-L-arabinofuranosides were prepared by chemo-enzymatic syntheses. These probes were designed as substrates to be used in assays of feruloyl esterase activity (EC 3.1.1.77). Color development in the assays only occurs when feruloyl esterase activity releases an intermediate chromogenic arabinoside that is a suitable substrate for alpha-L-arabinofuranosidase (EC 3.2.1.55), which in turn releases the free chromogenic group. The usefulness of these compounds was evaluated in both qualitative solid media-based assays and quantitative liquid assays that can be performed in microtiter plates using feruloyl esterases and arabinofuranosidases from various origins.

Esters to Carboxylic Acids: Acid-Catalyzed Hydrolysis
During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...
