Rhamnogalacturonan lyase from Aspergillus aculeatus
Overview
Rhamnogalacturonan lyase (RG-lyase) specifically recognizes and cleaves, alpha-1,4 glycosidic bonds between L-rhamnose and D-galacturonic acids in, the backbone of rhamnogalacturonan-I, a major component of the plant cell, wall polysaccharide, pectin. The three-dimensional structure of RG-lyase, from Aspergillus aculeatus has been determined to 1.5 A resolution, representing the first known structure from polysaccharide lyase family 4, and of an enzyme with this catalytic specificity. The 508-amino acid, polypeptide displays a unique arrangement of three distinct modular, domains. Each domain shows structural homology to non-catalytic domains, from other carbohydrate active enzymes.
About this Structure
1NKG is a Single protein structure of sequence from Aspergillus aculeatus with CA and SO4 as ligands. Full crystallographic information is available from OCA.
