Abstract
The new type of exopolygalacturonate lyase from Streptomyces nitrosporeus had a molecular weight between 32,400 to 39,000 in three different determination methods, a S020, w value of 3.4 S and an isoelectric point of pH 4.05. The purified enzyme contained a relatively large amount of aspartic acid, glycine and about 13% carbohydrate. The enzyme had higher affinity on 10~30% esterified polygalacturonate than on de-esterified polygalacturonate, but the degradation limit of the substrates by the enzyme was diminished by an increase in methyl ester groups of the substrates.This publication has 7 references indexed in Scilit:
