Fungal glucuronoyl esterases and substrate uronic acid recognition.
Glucuronoyl esterases are enzymes involved in microbial plant cell-wall degradation. In this study we purified and characterized two recombinant Phanerochaete chrysosporium glucuronoyl esterases, PcGE1 and PcGE2. The catalytic activity of these and previously described glucuronoyl esterases was investigated on new synthetic substrates, methyl esters of uronic acids and their glycosides, prepare...
متن کاملIdentification of genes encoding microbial glucuronoyl esterases.
One type of covalent linkages connecting lignin and hemicellulose in plant cell walls is the ester linkage between 4-O-methyl-D-glucuronic acid of glucuronoxylan and lignin alcohols. An enzyme that could hydrolyze such linkages, named glucuronoyl esterase, occurs in the cellulolytic system of the wood-rotting fungus Schizophyllum commune. Here we report partial amino acid sequences of the enzym...
متن کاملA New Functional Classification of Glucuronoyl Esterases by Peptide Pattern Recognition
Glucuronoyl esterases are a novel type of enzymes believed to catalyze the hydrolysis of ester linkages between lignin and glucuronoxylan in lignocellulosic biomass, linkages known as lignin carbohydrate complexes. These complexes contribute to the recalcitrance of lignocellulose. Glucuronoyl esterases are a part of the microbial machinery for lignocellulose degradation and coupling their role ...
متن کاملSubstrate Recognition and Specificity of Chitin Deacetylases and Related Family 4 Carbohydrate Esterases
Carbohydrate esterases family 4 (CE4 enzymes) includes chitin and peptidoglycan deacetylases, acetylxylan esterases, and poly-N-acetylglucosamine deacetylases that act on structural polysaccharides, altering their physicochemical properties, and participating in diverse biological functions. Chitin and peptidoglycan deacetylases are not only involved in cell wall morphogenesis and remodeling in...
متن کاملConformations of Uronic Acid Containing Polysaccharides
Analyses of X-ray diffraction patterns obtained from ordered specimens of a variety of polyuronides have provided the opportunity to examine their molecular geometry in the condensed phase. A brief review is given of the simpler homopolysaccharide components of alginic acid, followed by the connective tissue polydisaccharides: hyaluronic acid, the chondroitin suiphates, dermatan sulphate, hepar...
