glycoprotein

Straight edge: The miracle fruit (Synsepalum dulcificum), native to West Africa, contains a glycoprotein called miraculin that binds to taste receptors on the tongue and makes sour foods taste sweet.

神秘果：一种原产于西非的水果，内含一种叫神秘果蛋白的糖蛋白。 神秘果蛋白结合在味蕾上以后，吃酸的东西也感到是甜的。

What makes the fruit strange and miraculous, is miraculin (a sugar substitute), which is found in large quantities in the fruit, combined with a glycoprotein.

神秘果之所以奇妙神奇，是因水果中含有大量的神秘果素（代糖），合成一种糖蛋白（变味糖蛋白）。
