Crystal Structure Analysis of the Collagen-like Peptide, (PPG)4-OTG-(PPG)4
Stabilization of triple-helical structures of collagen peptides containing a Hyp-Thr-Gly, Hyp-Val-Gly, or Hyp-Ser-Gly sequence.
the rotated-inclined double crystal monochromator
12.5%(w/v) PEG 400, 0.1M MES buffer, pH 5.9, VAPOR DIFFUSION, SITTING DROP, temperature 277K
THIS PEPTIDE WAS CHEMICALLY SYSTHESIZED.
THIS SEQUENCE ADOPTS A TRIPLE-HELICAL STRUCURE SIMILAR TO THE COLLAGEN-HELIX.
THE STRUCTURE WAS REFINED UNDER THE TWINNING OPERATOR (H,-K,-L) AND TWINNING FRACTION 0.44 USING THE TWINNED DATA.
