分子式:
CAS号:

性质:催化植物细胞间质(即果胶质)水解成半乳糖醛酸和果胶酸的一类酶。按其作用方式,大致可分为三类:(1)原果胶酶(protopectinase),可使天然果胶转变为可溶性果胶。(2)果胶聚半乳糖醛酸酶(pectin polygalacturonase;PG),使果胶或果胶酸中α-1,4键分解,而生成半乳糖醛酸。(3)果胶甲酯水解酶(pectin methylesterase;PE),使果胶中甲酯水解,生成果胶酸。为使果胶完全分解,需要先用PE,再用PG。在果汁澄清中,亦同时用这两种酶。灰白色粉末或中黄色液体。最适作用pH值3.5~4.5,最适作用温度40~50℃。果胶酶广泛存在于植物和微生物中,动物细胞通常不能合成这类酶。工业上主要采用曲霉菌,如黑曲霉或青霉菌等生产。用于果汁加工(澄清果汁)、橘子脱囊衣以及制造浓缩果汁、果粉和低糖果冻。也可用于加强果酒的澄清效果,提高酒的收率。还可用于麻料脱胶和木材防腐等。
