Summary of qualifiers for feature keys 7. The GenBank, EMBL, and DDBJ nucleic acid sequence data banks have from their inception used tables of sites and features to describe the roles and locations of higher order sequence domains and elements within the genome of an organism.

The Feature Table documentation represents the shared rules that allow the three databases to exchange data on a daily basis. The range of features to be represented is diverse, including regions which: Feature key - a single word or abbreviation indicating functional group Location - instructions for finding the feature Qualifiers - auxiliary information about a feature 2.

Feature keys are arranged hierarchically, allowing complex and compound features to be expressed. Both location operators and the feature keys show feature relationships even when the features are not contiguous.

The hierarchy of feature keys allows broad categories of biological functionality, such as rRNAs, to be easily retrieved. A number of "generic" or miscellaneous feature keys have been added to permit annotation of features that cannot be adequately described by existing feature keys.

These generic feature keys will serve as an intermediate step in the identification and addition of new feature keys. The syntax has been designed to allow the addition of new feature keys as they are required.

Each end point of a feature may be specified as a single point, an alternate set of possible end points, a base number beyond which the end point lies, or a region which contains the end point.

The location field can contain operators or functional descriptors specifying what must be done to the sequence to reproduce the feature. For example, a series of exons may be "join"ed into a full coding sequence.

Features, such as open reading frames or sequences showing sequence similarity to consensus sequences, for which there is no direct experimental evidence can be annotated.

Therefore, the feature table can incorporate contributions from researchers doing computational analysis of the sequence databases. However, all features that are supported by experimental data will be clearly marked as such.

A consistent syntax allows machine extraction and manipulation of sequences coding for all features in the table. For example, an item in the feature table such as: The feature CDS is a coding sequence beginning at base 23 and ending at basehas a product called 'alcohol dehydrogenase' and is coded for by a gene called "adhI".

A more complex description: This feature, which is a partial coding sequence, is formed by joining elements indicated to form one contiguous sequence encoding a product called T- cell receptor beta-chain.

The following sections contain detailed explanations of the feature table design showing conventions for each component of the feature table, examples of how the format might be implemented, a description of the exact column placement of all the data items and examples of complete sequence entries that have been annotated using the new format.

The last section of this document describes known limitations of the current feature table design. Appendices II and III provide reference manuals for the feature table keys and qualifiers, respectively.

Appendix IV includes controlled vocabularies such as nucleotide base codes, modified base abbreviations, genetic code tables etc.

This document defines the syntax and vocabulary of the feature table. The syntax is sufficiently flexible to allow expression of a single biological entity in numerous ways. In such cases, the annotation staffs at the databases will propose conventions for standard means of denoting the entities.

Comments, corrections, and suggestions may be submitted to any of the database staffs. New format specifications will be added as needed. Component names may be no more than 20 characters long Feature keys 15, Feature qualifiers 20 and must contain at least one letter.iProLINK Help What is iProLINK?

As PIR focuses its effort on the curation of the UniProtKB protein sequence database, the goal of iProLINK is to provide curated data sources that can be utilized for text mining research in the areas of bibliography mapping, annotation extraction, protein named entity recognition, and protein ontology development.

This article introduces the basic concepts related to query expressions in C#. What is a query and what does it do?

A query is a set of instructions that describes what data to retrieve from a given data source (or sources) and what shape and organization the returned data should have.

A query is. The genetic code is the set of rules used by living cells to translate information encoded within genetic material (DNA or mRNA sequences) into feelthefish.comation is accomplished by the ribosome, which links amino acids in an order specified by messenger RNA (mRNA), using transfer RNA (tRNA) molecules to carry amino acids and to read the mRNA three nucleotides at a time.
