| Addtional Information | Synthesis Type : Ribosomal, Shepherin I and Shepherin II are two unique gly-rich AMPs generated from the same precursor protein using different polypeptide regions. Due to multiple His residues, their net charge depend on pH. IN TFE, no ordered structure was found by CD. The original has been replaced. Provided by Biswajit Mishra. 9/6/2012. |
