Hydrogen bonds are reported as (number of hydrogen bonds observed/number possible). For NMR structures, the number possible is the number of structures in the family. For crystal structures, the number possible is almost always 1. A hydrogen bond is assigned in an NMR structure if it is observed in at least 75% of the structures in the family.
For more information about the structures, see the Available Structures section of the home page for S100B.
