Figure 4. Protofilament interface in PHFs and SFs.

Figure 4

a. Packing between residues 332PGGGQ336 of the two protofilaments in PHFs. Inter-protofilament hydrogen bonds are shown in orange and green. Intra-protofilament hydrogen bonds are shown in yellow. b. Packing between residues 317–324 and residues 312–321 of the protofilaments in SFs. Additional density between the side chains of lysines 317 and 321 is shown as a green mesh.
