Frequency of occurence for amino acids located in chain 'E'

Contacts established between the selected residue type Histidine and other amino acids found within the spheare of radius=7 Å.

The center of the spheare is located at the Alpha carbon Atom of the Histidines.

The contacting amino acid is counted in if its Alpha carbon Atom is encountered withinn the space occupied by the sphere of 7 Å radius.

Selected amino acid type Histidine was also selected to belong to the secondary structure element: All
