Cucumisin (EC 3.4.21.25) isolated from prince melon fruit is a plant serine protease. Its milk-clotting activity was compared with plant cysteine proteases such as papain (EC 3.4.22.2) and ficain (EC 3.4.22.3). Cucumisin was more stable than papain under the condition of pH 7.1, 37 degrees C for 24 h. The milk-clotting activity of cucumisin was the same to that of papain and was half value of that of ficain.
从哈密瓜果实中分离出的黄瓜蛋白酶（EC 3.4.21.25）是一种植物丝氨酸蛋白酶。将其凝乳活性与木瓜蛋白酶（EC 3.4.22.2）和无花果蛋白酶（EC 3.4.22.3）等植物半胱氨酸蛋白酶进行了比较。在pH 7.1、37℃条件下处理24小时，黄瓜蛋白酶比木瓜蛋白酶更稳定。黄瓜蛋白酶的凝乳活性与木瓜蛋白酶相同，是无花果蛋白酶凝乳活性的一半。
