What is new in PPDB:
- Sept 2017. Improved proteostasis functions. The functional bin annotation system was expanded to include assignment of (candidate) peptidases to MEROPS families and clans in a hierarchical manner. All (candidate) peptidases and peptidase inhibitors, as well as known auxiliary components of peptidase (systems) such as the CLP chaperones and 26S lid and base, are assigned to be within bin 29.5 ‘protein.degradation’. Nearly 700 Arabidopsis proteins have a primary functional assignment to this bin 29.5. More information can be found in Majsec et al (2017) The Plant Cell. The Plastid and Mitochondrial Peptidase Network in Arabidopsis thaliana: A Foundation for Testing Genetic Interactions and Functions in Organellar Proteostasis.
- August 2017. Updated protein subcellular annotation for Arabidopsis. Following manual curation, a total of 3598 Arabidopsis proteins (counting just one protein model per gene) now have an assignment location to one or more subcellular locations. For instance, plastids - 1718 proteins; mitochondria – 429 proteins; peroxisome - 156 proteins; cytosol – 503 proteins; plasma membrane – 298 proteins.

Bi-directional BLAST search results to Arabidopsis thaliana (TAIRv7), rice (v7), PFAM domains, subcellular localization predictions (TargetP) and protein transmembrane predictions (TMHMM) are available.

- experimental data on the comparative analysis of maize bundle sheath and mesophyll membrane proteomes available - published in (Majeran et al., 2008).
The name of PPDB is changed to Plant Proteome Database
We have captured data from 58 proteomics publications (Arabidopsis and
). The data set have been deposited into PPDB.
newly curated location based on experimental evidence for hundreds of plastid
proteins, including nucleoids, ribosomes, and plastoglobules.
new experimental output parameters: experimental sequence coverage from
internal MS data, subcellular localization based on GFP/YFP for >1000
proteins - from the SUBA database.
experimental protein sequence coverage display by internally mass
spectrometry data (via 'pop-up' windows on each protein page report). -
experimental MS/MS data on the peripheral and lumenal proteome of A. thaliana -
published in (Giacomelli et al., 2006).
experimental data on the plastoglobule proteome of A. thaliana available -
published in (Ytterberg et al., 2006).
Arabidopsis gene models are updated to TAIR v6.0. All MS/MS-based proteins
identifications published since summer 2004 are reanalyzed against v6.0.
