PDB molecule of the month

Now let's go back to the Protein Data Bank one final time. This has an interesting feature called Molecule of the Month. Each month a short, easy-to-read article is written about a selected molecule of known structure. The protein you have been investigating is included in this list. On the PDB Home Page in the 'Featured Molecules' section click on the 'List view or archive by : Title' option. Scroll down or use the alphabetical links to find the article on the protein you have been investigating.
