RHAMNOGALACTURONASE B FROM ASPERGILLUS ACULEATUS IS A RHAMNOGALACTURONAN ALPHA-L-RHAMNOPYRANOSYL-(1-]4)-ALPHA-D-GALACTOPYRANOSYLURONIDE LYASE

摘要

The recently described rhamnogalacturonase B, which is able to degrade ramified hairy regions of pectin, was found to be a rhamnogalacturonan alpha-L-rhamnopyranosyl-(1-->4)-alpha-o-galactopyranosyluronide lyase. The cleavage site and mechanism differ from that of the previously described rhamnogalacturonase A, which is a hydrolase and can now be termed rhamnogalacturonan alpha-D-galactopyranosyluronide-(1-->2)-alpha-L-rhamnopyranosyl hydrolase.
