The NMPDR keyword search works like a typical search engine. You type in the appropriate words, and a list of genes will come back. Our keyword database contains millions of words, including vitamins, aldolase, and pyrophosphokinase. The NMPDR looks at nine specific data items when computing the keywords for a gene. The table below shows each of the nine steps along with the keywords derived by that step for the gene fig|171101.1.peg.269, a dual-role protein encoding gene for Streptococcus pneumoniae r6 that has 40 keywords.
| FIG gene identifier | 171101.1.peg.269 |
| The aliases | 15902313, kegg|spd:SPD_0272, kegg|spr:spr0269, NP_357863.1, sp|P59657, spr0269, sulD, tr|Q04MF8, uni|P59657, uni|Q04MF8 |
| All words in the functional role | Dihydroneopterin, aldolase 2-amino-4-hydroxy-6-hydroxymethyldihydropteridine, pyrophosphokinase amino, hydroxy, hydroxymethyldihydropteridine |
| The genome ID | 171101.1 |
| All words in the taxonomy | bacteria, firmicutes, lactobacillales, streptococcaceae, streptococcus, pneumoniae, r6 |
| The subsystem names and classifications | folate, biosynthesis, cofactors, vitamins, prosthetic, groups, pigments, folates, pterines |
| The EC number | 2.7.6.3, 4.1.2.25 |
| The subsystem role | 2-amino-4-hydroxy-6-hydroxymethyldihydropteridine, pyrophosphokinase, amino, hydroxy, hydroxymethylhydroperidine |
| Special Keywords | essential |
Notes
- Some keywords appear twice.
- In the functional role, hyphenated words are stored in their full form (2-amino-4-hydroxy-6-hydroxymethyldihydropteridine) as well as broken up on the hyphen boundaries (amino- hydroxy hydroxymethyldihydropteridine).
- Keywords are case-insensitive
- Special keywords indicate attributes of the gene. Most of these are incomplete: for example, we know certain genes are virulence-associated, but for most of the genes we have no virulence data.
- virulence, which indicates the gene participates in the process of helping the organism to damage its host. This attribute is incomplete.
- essential, which indicates that the gene is essential to to the survival of the organism. This attribute is incomplete.
- iedb, which indicates that the gene is listed in the Immune Epitope Database
Advanced Keyword Searching
Normally, the search process selects the genes relevant to all the words in the keyword box. You can modify the default behavior by prefixing control characters to the keywords.
| Meaning|Example|Explanation of Example |
| negation|2.7.6.3 -firmicutes: search for all genes with EC number 2.7.6.3 that are not in firmicutes |
