WELCOME TO P3DB!

P3DB was established with an overall objective to provide a resource of protein phosphorylation data from multiple plants.

P3DB version 1.0 was constructed with a dataset from oilseed rape (Brassica napus var. Reston) developing seed obtained using a combination of data-dependent neutral loss and multistage activation mass spectrometry. The dataset includes 14,670 non-redundant phosphorylation sites from 8,894 phospho-peptides in 6,382 substrate proteins.

In P3DB version 1.1, a phosphorylation dataset on Arabidopsis thaliana from Sugiyama et al., 2008 was deposited. This dataset contains 2172 phosphorylation sites.

More mass-spectrometry-based protein phosphorylation data will be collected and deposited into this database from large-scale studies of Arabidopsis thaliana and soybean (Glycine max var. Maverick).

Plant phosphorylation data from other, previous investigations will also be integrated into the P3DB at a later date.
