-
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.

[https://www.uniprot.org/uniprot/VMO1_CHICK VMO1_CHICK] Exact function not known, component of the outer membrane of the vitelline layer of the egg. Seems to be able to synthesize N-acetylchito-oligosaccharides (n=14-15) from hexasaccharides of N-acetylglucosamine in a manner similar to the transferase activity of lysozyme.
