wwPDB validation report of PDB entry 6NDY

Vacuolar protein sorting-associated protein 4

Vps4, DOA4-independent degradation protein 6, Protein END13, Vacuolar protein-targeting protein 10

Vps4 with Cyclic Peptide Bound in the Central Pore

The entry contains two cyclic peptides having the following sequences:
GGDEIVNKVLGGSSGGASASASASGGKGCK
GGDEIVNKVLGGSSGGDEIVNKVLGGKGCK
Only two segments of the peptides were observed: a forward and return portions.
The loops between the forward and return portions are unobserved.
In addition, the peptide, as resolved, represents an average of the two peptides.
The averaged portion is designated as UNK residues.
