About the Database

The possible linear polypeptides that consist of 20 kinds of amino acids and having molecular weights smaller than 1000 were computationally calculated and stored in the Pep1000 database.

Last updated.

In the description field, amino acid compositions are described with one letter code and their numbers. As the leucine and isoleucine has the same molecular weight, they are described as [L|I].

In the case that the same molecular formula are given by more than two amino acid compositions, they are enumerated in the 'description' column separating by comma.



Search Limit: 100

The maximum record number that returns for a single query is 100 as default. The number can be set to a smaller one by setting the "limit" parameter.

When the number of search results exceeds the maximum number, the value of "is-limited" will be set to "true". It means that not all of the search results were written in the returned text, so please be careful to discuss about the results.

The "is-limited" value is written in the returned text when the "output" parameter has been set to "txth" or "xml".




Updating Schedule

Not planned.
