图3 甘蔗、水稻、半夏和菠菜的PetC成熟蛋白三级结构预测 黄色箭头处为PetC蛋白的[2Fe-2S]结合域; 蓝色和红色箭头所指位点为氨基酸链的N端和C端; 绿色箭头所指位点为α螺旋。图A中白色箭头表示ScPetC与其他植物PetC的差异α螺旋所在位置。

Fig. 3 Predicted third structure of mature PetC in Saccharum spp. hybrids, Oryza sativa, Pinellia ternate, and Spinacia oleracea Yellow arrow is the conservative binding domain [2Fe-2S] of PetC; blue and red arrows represent the N-terminus and C-terminus of the amino acid chain; green arrows represent α helix. White arrow represents the α helix in sugarcane that is different from other plants of tertiary structure in figure A.
