刚刚开始接触同源建模,请教一下根据下面的数据能否同源建模:
1.Here, we report the crystal structure of a peptidetransporter from the bacterium Shewanella oneidensis,PepTSo, which shows a high degree of sequence conservationwithin the TM region (-30% identity) to the mammalianPepT1 and PepT2 proteins.
2.PepTSo has two additional TM helices, HA and HB, which are inserted into the cytoplasmic loop connecting the N- and C-terminal bundles. These form a hairpinlikestructure in the membrane that packs against the peripheryof the protein.Their role is currently
unclear. The apparent absence of these helices in the fungal,plant and metazoan protein sequences, however, suggests they do not contribute to any conserved transport mechanism.
文献中讲到仅仅是TM区域有30%的保守性,而且多了两个helices HA和HB,但是对药物作用通道没有影响,这样的结构能够同源建模吗? |
