红细胞内寄生的疟原虫所需的氨基酸主要来源于宿主的血红蛋白。现已发现在疟原虫的酸性食物泡中有半胱氨酸蛋白酶和天冬氨酸蛋白酶的存在,它们附着于变性或正常的血红蛋白表面。在以往的研究中作者发现,疟原虫的半胱氨酸蛋白酶与其它木瓜蛋白酶 The amino acids required for erythrocytic parasitic Plasmodium are mainly derived from the host’s hemoglobin. It has now been found that in acidic matrices of the malaria parasite the presence of cysteine ​​proteases and aspartic proteases, which attach to denatured or normal hemoglobin surfaces. In previous studies, the authors found that the cysteine ​​proteases of Plasmodium and other papain
