The data in the database may be explored in two ways. They may be browsed by one of the three categories: kingdom (archaea, bacteria, eukaryotes and viruses), organism and type of recoding. The data may also be searched directly by key words that can be inserted into the search field. Searches that use regular expressions are allowed. The output of a database search is a list of Recode-2 entries in a short format that includes organism name, kingdom, genus, type of recoding event, status of Figure 2 shows an example of sequence annotation for the human oaz1 gene, alongside a diagram of a stimulatory RNA secondary structure, and the Recode-1 logo.
