Searches or browses for structures by Medical Subject Heading Terms (MeSH terms). The Medical Subject Heading Browser is a hierarchical representation of the National Library of Medicine's controlled vocabulary thesaurus (http://www.nlm.nih.gov/mesh). This query searches for MeSH terms contained in PubMed abstracts related to the PDB structures.
The Medical Subject Headings Browser permits the user to navigate through the MeSH hierarchy to arrive at the subset of particular interest. The browser opens up the top level in the hierarchy. Clicking on the arrow/folder icons expands the respective nodes. Clicking on the name of the node will retrieve all PDB IDs assigned to that node.
