Soybean Proteome Database stores soybean protein data obtained from gel-based and gel-free proteomic techniques.
The goal of this database is to provide proteomic information for functional analyses. The majority of the data is focused on soybean, which is an important crop to supply vegetable oil and protein but has high sensitivity in abiotic stresses.
It was originally constructed using soybean protein data separated by two-dimensional polyacrylamide gel electrophoresis (2D-PAGE, gel-based proteomics database). In 2015, data of mass spectrometry-based label-free quantitative proteomics (gel-free proteomics database) was added.
Furthermore, the database integrates multiple omics. The whole database is coordinated based on a scheme of differential omics to identify time-variant proteins under flooding stress.
