Table 2. Amino-acid interactions of PIYDIN in the 31-peptide complex (PDB entry 7njz) with RoAb13.

These were very similar in the PIYDIN-only study (see footnote).

Amino acid in PIYDIN	Nearest-neighbor amino acids of RoAb13 (within 3.5 Å)
P	Tyr98L, Tyr100L; Ile223H of symmetry equivalent
I	Thr99L †, Gly218L; Gly220H, Pro221H of symmetry equivalent
Y	Asp61H, Arg64H; Cys220L of symmetry equivalent
D	Ile12C, Asn13C
I	Tyr98L
N	Asp11C

^†This distance was 5 Å in PDB entry 7njz but was 3.5 Å in the PIYDIN-only study (PDB entry 7nw3).
