This is the Influenza B Neuraminidase and its complex with sialic acid.

Two calcium binding sites have been identified. One of them, previously undescribed, is located between the active site and a large surface antigenic loop. The calcium ion is octahedrally co-ordinated by five oxygen atoms from the protein and one water molecule.

This model chain A and chain B is same. This figure, domain indicate spacefill and cpk color.
