String Database

Definition

A string database is a type of biological database that stores sequences of nucleotides or proteins in a format that allows for efficient searching and retrieval. These databases are essential for proteomics and genomics, as they provide researchers with a means to access large amounts of sequence data, facilitating the comparison and analysis of genes and proteins across different organisms.
