多聚半乳糖醛酸(内切)酶(Polygalacturonase, EC 3.2.1.15, 简称PG或endo-PG)多聚-α-1,4-半乳糖醛酸聚糖水化酶(poly-galacturonide glycanohydrase)的通用名,是可分解果胶或果胶酸酶类中的一种,亦称果胶酶(pectic enzyme)或果胶解聚酶(pectin depolymerase)。是水解组成果胶酸的D-半乳糖醛酸α-1,4-糖苷键的酶,在食品工业特别是果汁澄清中有重要意义。
多聚半乳糖醛酸酶(Polygalacturonase,PG)是一种细胞壁结合蛋白,可以催化果胶分子中a-1,4-聚半乳糖醛酸的裂解,参与果胶的降解,使细胞壁结构解体,导致果实软化。
