This is an example page. Edit appropriately for your project. Upon completion, delete instructions in green.

1. Add a citation to the primary reference at the end of the title above: you should all read this paper!

Edit the title section to add the command ^[2] following the pdb code. Go to [1] and search for your pdb code. Go down to the abstract and click "Search on Pubmed". In pubmed, copy the PMID code you see right below the abstract, and paste it to replace xxx after PMID.

Overall Structure

The ligand binding domain of the aspartate receptor () ) is a dimer of two 4-helix bundles that is shown here with the bound.^[3] In this the N and C termini are at the bottom of the structure; this is where the connections to the transmembrane helices have been truncated.

Binding Interactions

When the protein is colored according to , residues at the ligand site are the most conserved.

Interactions that stabilize ligand binding^[4] include hydrogen bonding from Tyr149 and Gln152 backbone carbonyls and Thr154 sidechain OH to the and hydrogen bonding from the sidechain nitrogens of Arg64, Arg69, and Arg73 to the two .
