PECTIN LYASE A
Overview
BACKGROUND: Microbial pectin and pectate lyases are virulence factors that, degrade the pectic components of the plant cell wall. The homogalacturan, backbone of pectin varies in its degree of methylation from the highly, methylated and relatively hydrophobic form known as pectin, to the fully, demethylated and highly charged form known as pectate. Methylated and, demethylated regions of pectin are cleaved by pectin lyase and, calcium-dependent pectate lyases, respectively. Protein engineering of, lyases specific for particular patterns of methylation, will yield, modified pectins of high value to the food and pharmaceutical industries., RESULTS: The crystal structures of pectin lyase A from two strains of, Aspergillus niger, N400 and 4M-147, have been determined at pH 6.5 (2.4 A, ...
