Fig 9. mHABP electron density. Side-chain atoms for p2, p3, p5, p7 and p8 in 25608.37 and 10022.43.

Fig 9

The figure shows the side-chains for upwardly-oriented residues pointing to TCR-contacting residues. Polar amino acids present in p2, p5 and p8, displaying their non-bonding free electron pairs and π orbital surfaces shown in blurred red while σ orbitals for apolar ones present in p3 and p7 are shown by yellow surfaces. The φ angles (≤ -64°) in p7P (25608.37), p5P (32958.2), p7P (24254.31), p3P and p8P (10022.43) oriented this residue to make contact with the TCR.
