Expanding the feruloyl esterase gene family of Aspergillus niger by characterization of a feruloyl esterase, FaeC.
A feruloyl esterase (FAE) from Aspergillus niger N402, FaeC was heterologously produced in Pichia pastoris X-33 in a yield of 10mg/L. FaeC was most active at pH 7.0 and 50°C, and showed broad substrate specificity and catalyzed the hydrolysis of methyl 3,4-dimethoxycinnamate, ethyl ferulate, methyl ferulate, methyl p-coumarate, ethyl coumarate, methyl sinapate, and methyl caffeate. The enzyme r...
متن کاملA CESA from Griffithsia monilis (Rhodophyta, Florideophyceae) has a family 48 carbohydrate-binding module
Cellulose synthases form rosette terminal complexes in the plasma membranes of Streptophyta and various linear terminal complexes in other taxa. The sequence of a putative CESA from Griffithsia monilis (Rhodophyta, Floridiophyceae) was deduced using a cloning strategy involving degenerate primers, a cDNA library screen, and 5' and 3' rapid amplification of cDNA ends (RACE). RACE identified two ...
متن کاملFeruloyl esterase
Feruloyl esterase forms a part of the enzyme complex that acts collectively and synergistically to completely hydrolyze xylan to its monomers. The enzyme has found potential uses in a wide variety of applications of interest to the agrifood and pharmaceutical industries. This review describes the enzymology of feruloyl esterases involved in xylan degradation. The occurrence of feruloyl esterase...
متن کاملComputational investigation of glycosylation effects on a family 1 carbohydrate-binding module.
Carbohydrate-binding modules (CBMs) are ubiquitous components of glycoside hydrolases, which degrade polysaccharides in nature. CBMs target specific polysaccharides, and CBM binding affinity to cellulose is known to be proportional to cellulase activity, such that increasing binding affinity is an important component of performance improvement. To ascertain the impact of protein and glycan engi...
متن کاملIdentification and glucan-binding properties of a new carbohydrate-binding module family.
The C-terminal 191-residue module of Cel5A from the alkalophilic Bacillus sp. 1139 comprises a carbohydrate-binding module (CBM) belonging to a previously unidentified family that we have classified as CBM family 28. This example, called CBM28, bound specifically to cello-oligosaccharides and mixed beta-(1,3)(1,4)-glucans (barley beta-glucan) with association constants of approximately (1-4)x10...
