[phenixbb] Molecular replacement of cyclic polypeptide with non-standard amino acid

Dear all, I have collected an XRD data from a crystal of cyclic polypeptide with non-standard amino acid (2,4-diaminobutyric acid). Is it possible to solve the structure by molecular replacement? Or does anyone have any suggestion for solving the structure? Thank you very much for your kind help. --- Best regards, Ariela Samantha PhD Candidate Department of Structural Biology School of Molecular Sciences The University of Western Australia Bayliss Building room 4.26 Phone +61 8 6488 ext. 3163
