Average Crystal Structure of (Pro-Pro-Gly)9 at 1.0 angstroms Resolution
PEG400, acetic acid, sodium azide, VAPOR DIFFUSION, HANGING DROP, temperature 283K
The peptide was chemically synthesized. The sequence of the peptide is naturally found in collagens.
The structural model for collagen proposed by Okuyama (1981)
THE ENTIRE 27 RESIDUE LONG PEPTIDE CAN BE GENERATED FROM THE SUBMITTED ASYMMETRIC UNIT BY APPLYING THE FOLLOWING TRANSLATIONS (USING FRACTIONAL COORDINATES): CHAIN A: TRANSLATE RESIDUES 2 - 7 BY (0 0 1), AND RESIDUES 1-7 BY (002), (003), (004) AND RESIDUE 1 BY (005). CHAIN B: TRANSLATE RESIDUES 33-37 BY (0 0 1), AND RESIDUES 31-37 BY (002), (003), (004) AND RESIDUE 31-32 BY (005). CHAIN C: TRANSLATE RESIDUES 64-67 BY (0 0 1), AND RESIDUES 61-67 BY (002), (003), (004). THIS WILL RESULT IN A MOLECULE WITH A TOTAL OF 81 RESIDUES, 27 IN EACH CHAIN.
