| 2.Helix,Sheet等的预测结果: |
| 方法:向The
PredictProtein server提交多肽序列.预测实现方法参见Rost
B(1996) |
| 结果:结果包括两个部分,Fig1为图象化以后的结果图,直接的预测结果请参看这里 |

| 3.Motif预测: |
| 方法:在prosit中通过序列比对,找到蛋白中可能含有的序列的motif. |
| 结果:下表中列出了改序列中可能含有的motif.其中,数字表示motif的第一个氨基酸在整个序列中的位置,后面的字母表示氨基酸序列. |

| 4.穿膜片断预测结果 |
| 这是用The
PredictProtein Server预测二阶结构的结果之一,下表列出了可能的穿膜片断以及整个肽链在膜内和膜外的分布情况.由于以下是序列扫描以后的结果,所有有些非膜蛋白也有可能被预测为有穿膜序列. |
