Extraction and Assay of Ferulic Acid Esterase From Malted.

Feruloyl esterase activity was first detected in culture filtrates of Streptomyces olivochromogenes (Mackenzie et al., 1987) and has thereafter also been reported for some hemicelluloyltic fungi. A partially purified feruloyl esterase from S. commune liberated hardly any ferulic acid without the presence of xylanase ( Mackenzie and Bilous, 1988 ).

Catalysts 2018, 8, 242 2 of 22 1. Introduction Feruloyl esterases (EC 3.1.1.73, FAEs) are a subclass of carbohydrate esterases generally known for their role as accessory enzymes during the enzymatic hydrolysis of lignocellulosic biomass, being able.

Optimization of enzymatic synthesis of L-arabinose ferulate catalyzed by feruloyl esterases from Myceliophthora thermophila in detergentless microemulsions and assessment of its antioxidant and cytotoxicity activities. . Feruloyl esterase.

Ferulic acid is one of the major phenolic acids in plants and can be found esterified to plant cell wall components, but also as long-chain n-alkyl and steryl esters. Microbial feruloyl esterases may play a role in the bioavailability of phenolic acids during human and animal digestion. It is therefore of interest if feruloyl esterases are capable of hydrolyzing nonpolar ferulic acid esters.

In the present study, the encoding sequence of putative feruloyl esterase A (AfFaeA) was cloned from genomic DNA from Aspergillus flavus and expressed in Pichia pastoris. The purified recombinant AfFaeA had apparent relative molecular mass of about 40,000 and had an optimum pH of 6.0, although it was stable at pH values ranging from 4.5 to 8.0.

An extracellular feruloyl esterase (FAE-II) from the culture filtrates of Fusarium oxysporum F3 was purified to homogeneity by SP-Sepharose, t-butyl-HIC and Sephacryl S-200 column chromatography. The protein corresponded to molecular mass and pI values of 27 kDa and 9.9, respectively. The enzyme was optimally active at pH 7 and 45 degreesC.

The enzyme was identified as a monomer protein using size-exclusion chromatography. Its optimum temperature and pH were, respectively, 40 degrees C and pH 5. Its activity was stable at pH 3 to 5. The enzyme was combined with xylan and starch, but it was absorbed by cellulose. The km of the feruloyl esterase was 0.0019% (0.01 mM).

A single amino acid pattern (GGG(A)X motif) in hydrolases controls their activity towards tertiary alcohols. Consequently, a range of active lipases and esterases which catalyze the efficient conversion of acetates of different tertiary alcohols (see scheme) and thereby facilitate access to this class of building blocks for organic synthesis, flavors, and fragrances was identified by sequence.

The feruloyl esterase (StFaeC) produced by Sporotrichum thermophile transfered the feruloyl group to d-arabinose using a mixture of n-hexane, t-butanol and water. About 45% conversion of d-arabinose to the feruloylated derivative was achieved.. Chemoenzymatic synthesis, Feruloyl esterases.
