FunFam 203: Feruloyl esterase B

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Acetylxylan esterase. [EC: 3.1.1.72]
Deacetylation of xylans and xylo-oligosaccharides.
  • Catalyzes the hydrolysis of acetyl groups from polymeric xylan, acetylated xylose, acetylated glucose, alpha-napthyl acetate, p-nitrophenyl acetate but not from triacetylglycerol.
  • Does not act on acetylated mannan or pectin.

Feruloyl esterase. [EC: 3.1.1.73]
Feruloyl-polysaccharide + H(2)O = ferulate + polysaccharide.
  • Catalyzes the hydrolysis of the 4-hydroxy-3-methoxycinnamoyl (feruloyl) group from an esterified sugar, which is usually arabinose in 'natural' substrates.
  • p-nitrophenol acetate and methyl ferulate are poorer substrates.
  • All microbial ferulate esterases are secreted into the culture medium.
  • They are sometimes called hemicellulase accessory enzymes, since they help xylanases and pectinases to break down plant cell wall hemicellulose.
