plprot - Arabidopsis thaliana chloroplast database

Database contains all relevant information about proteins identified from Arabidopsis thaliana chloroplasts by a shotgun proteomics approach
[please cite: T. Kleffmann, D. Russenberger, A. von Zychlinski, W. Christopher, K. Sjolander, W. Gruissem and S. Baginsky. The Arabidopsis thaliana chloroplast proteome reveals pathway abundance and novel protein functions
(Current Biology (2004) 14, 354-362 )].

For data search and output the relevant fields have to be checked. Fields contain the following information:
  • - Gene ID: Arabidopsis thaliana gene identifier from the TIGR database (The Institute of Genomic Research: http://www.tigr.org)
  • - Protein Description: Contains protein annotation
  • - Sequence: Amino acid sequence of identified protein from the TIGR database
  • - Fractionation: Fractionation strategy MDC-pre-fractionation by multidimensional chromatography ENV-pre-fractionation by envelope membrane preparation
  • - TargetP: Prediction of subcellular localization of identified protein by TargetP (http://www.cbs.dtu.dk/services/TargetP/)
  • - RNA Exp: arbitrary RNA expression level of the identified protein on the Affymetrix GeneChip® (data were normalized using a target value of 1000)
  • - RNA Exp det: contains the detection calls A-absent (p-value > 0.6), P-present (p-value <= 0.5) and M-marginal (p-value between 0.5 and 0.6).
  • - Relative protein abundance [No of Ions/MW]: The number of identified tryptic peptides per protein, divided by its molecular mass provides a semiquantitatve value for the relative abundance of each protein (for review see: Greenbaum et al., Comparing protein abundance and mRNA expression levels on a genomic scale. Genome Biol. 2003; 4, 117)
