- ↑ Alpha carbons are spacefilled to a radius of 3.5 Å to make domains look solid. The van der Waals radius of carbon is 1.7 Å.
- ↑ 3.0 3.1 3.2 Sequence numbers start with 1 at the second residue in the genomic sequence, since the initial Met is believed to be removed by N-terminal methionine aminopeptidase. The N-terminal genomic sequence (Uniprot FLGE-CAMJE Q0P7Q2) is MMRSLW, while the N-terminal sequence of the mature protein is believed to be MRSLW.
- ↑ Polar residues are Arg, Asn, Asp, Gln, Glu, His, Lys, Ser, Thr, Tyr. There are no Tyr or Trp lining the channel.
- ↑ 5.0 5.1 The monomer chain in the above scenes is chain "e". It is one of 21 chains in the 55-chain model that has the maximum number of contacting atoms (216) from other chains. It is also one of 28 chains that have the maximum number of atoms (51) from neighboring chains contacting the L-stretch. The L-stretch is also contacted by 31 atoms from other residues in the same chain (not shown).
- ↑ 6.0 6.1 "Contacting" is defined as likely hydrogen bonds, plus likely apolar interactions. Likely hydrogen bonds: oxygens or nitrogens within 3.5 Å of oxygens or nitrogens in a neighboring monomer. Apolar interactions: carbons or sulfurs within 4.0 Å of carbons or sulfurs in a neighboring monomer.
- ↑ Contacting atoms are rendered at radius 3.1 Å. For comparison, the van der Waals radius of carbon is 1.7 Å.: A. Bondi, J. Phys. Chem. 68:441 (1964).
