CRYSTAL STRUCTURE OF VITELLINE MEMBRANE OUTER LAYER PROTEIN I (VMO-I): A FOLDING MOTIF WITH HOMOLOGOUS GREEK KEY STRUCTURES RELATED BY AN INTERNAL THREE-FOLD SYMMETRY
Overview
The crystal structure of vitelline membrane outer layer protein I (VMO-I), which is isolated from the vitelline membrane outer layer of hen's eggs, has been determined by the multiple isomorphous replacement method and refined to an R-factor of 18.8% at 2.2 A resolution. The main chain folds into an unusual structure that consists of three beta-sheets forming Greek key motifs, which are related by an internal pseudo three-fold symmetry. The internal portion surrounded by these three beta-sheets is filled with hydrophobic side chains. This conformational feature coincides with three internal repeats in the sequence. Although a similar fold exists in the second domain of delta-endotoxin, there are significant structural differences between the two proteins, with the three-fold symmetry being most regular in VMO-I.
About this Structure
