| الوصف: | The mechanism of hydrolysis of various pectic substrates by highly purified endo-polygalacturonase from Rhizopus arrhizus (RAPG) was investigated. RAPG hydrolyzed pectic acids through a random attack mechanism. Under controlled conditions, after hydrolysis of the pectic acid (DP = 134) by RAPG for 48 hr at 30°C, the major end products were monogalacturonic acid (6.5%), dimer (18.0%), trimer (55.0%), tetramer (6.6%), pentamer (5.1%), hexamer (3.0%), and small amounts of other oligomers. RAPG reacted more quickly on pectic acids of intermediate molecular weight (DP = 24), and favored pectic acid rather than pectinic acid and pectins. |
