  1. Structure prediction TTCCPSIVARSNFNVCRLPGTPEAICATYTGCIIIPGATCPGDYAN At present, there is still no method available that can consistently predict correct structure from a general sequence NCKU

  2. Homology Modeling If the sequence identity between two sequences A and B is greater than 25%, and if B has a known structure, then it is possible to predict the structure of the sequence A by homology modeling method. NCKU

  3.

  5. Raw sequence Use templates to build the structure of the homologous sequence Predicted structure NCKU

  6. Use SwissPDBViewer as an Example to build a structure of the following sequence MQQPMNYPCP QIFWVDSSAT SSWAPPGSVF PCPSCGPRGP DQRRPPPPPP PVSPLPPPSQ PLPLPPLTPL KKKDHNTNLW LPVVFFMVLV ALVGMGLGMY QLFHLQKELA ELREFTNQSL KVSSFEKQIA NPSTPSEKKE PRSVAHLTGN PHSRSIPLEW EDTYGTALIS GVKYKKGGLV INETGLYFVY SKVYFRGQSC NNQPLNHKVY MRNSKYPEDL VLMEEKRLNY CTTGQIWAHS SYLGAVFNLT SADHLYVNIS QLSLINFEES KTFFGLYKL NCKU
