What major online databases contain DNA and protein sequences?
Of these, the most important are the equivalent DNA databases European Molecular Biology Laboratory (EMBL), GenBank and DNA Databank of Japan (DDBJ), and the protein databases Swiss-Prot and TrEMBL.
What are the protein sequence database?
The Protein database is a collection of sequences from several sources, including translations from annotated coding regions in GenBank, RefSeq and TPA, as well as records from SwissProt, PIR, PRF, and PDB. Protein sequences are the fundamental determinants of biological structure and function.
Is Swiss-Prot a secondary database?
SWISS PROT is a protein sequence database. Annotations in the database provide all the information regarding the structure and function of a particular protein along with its functions and modifications if any. The data is all primary and easily accessible. It is thus a primary database.
Which is a major protein sequence database?
The leading universal curated protein sequence database is Swiss-Prot (http://www.ebi.ac.uk/swissprot/index.html), which contained as of November 2003 (release 42.6) 140 000 curated sequence entries from over 8300 different species.
How do you convert DNA to protein sequence?
During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.
What is protein sequence?
The sequence of a protein is usually notated as a string of letters, according to the order of the amino acids from the amino-terminal to the carboxyl-terminal of the protein. Either a single or three-letter code may be used to represent each amino acid in the sequence.
Which of the following is first protein sequence database?
Protein Information Resource Protein Sequence Database
The oldest universal curated protein sequence database is the Protein Information Resource Protein Sequence Database (PIR-PSD) (http://pir.georgetown.edu/).
