TLDR
An analysis of 715 Arabidopsis thaliana sequences from SWISS‐PROT suggests that the ChloroP method should be useful for the identification of putative transit peptides in genome‐wide sequence data.
Abstract
We present a neural network based method (ChloroP) for identifying chloroplast transit peptides and their cleavage sites. Using cross-validation, 88% of the sequences in our homology reduced training set were correctly classified as transit peptides or nontransit peptides. This performance level is well above that of the publicly available chloroplast localization predictor PSORT. Cleavage sites are predicted using a scoring matrix derived by an automatic motif-finding algorithm. Approximately 60% of the known cleavage sites in our sequence collection were predicted to within +/-2 residues from the cleavage sites given in SWISS-PROT. An analysis of 715 Arabidopsis thaliana sequences from SWISS-PROT suggests that the ChloroP method should be useful for the identification of putative transit peptides in genome-wide sequence data. The ChloroP predictor is available as a web-server at http://www.cbs.dtu.dk/services/ChloroP/.

Expression of recombinant proteins lacking methionine as N-terminal amino acid in plastids: human serum albumin as a case study.

TL;DR: Analysis of several foreign proteins expressed in tobacco chloroplasts showed a cleavage pattern in accordance to that of endogenous proteins, which should be taken into account when recombinant proteins with N-terminus relevant for its function are expressed in plastids.

Manipulation of Carotenoid Metabolic Flux by Lycopene Cyclization in Ripening Red Pepper ( Capsicum annuum var. conoides) Fruits.

TL;DR: Although capsanthin was accumulated in ripened fruits, the quantification demonstrated a strong induction of CaCCS1 at the breaker stage, together with the simultaneous repression of CaLCYE1 and the decrease of lutein content, suggesting the involvement of Ca CCS1 in competing against Ca LCYE1 for synthesizing carotenoids of the β,β-branch.

Identification of a Chloroplast Ribonucleoprotein Complex Containing Trans-splicing Factors, Intron RNA, and Novel Components

TL;DR: The yeast-two hybrid system provides evidence in support of direct interactions between Rab1 and four trans-splicing factors, and chloroplast-localized Raa4-binding protein 1 (Rab1), which specifically binds tscA RNA from the tripartite psaA group II intron.

Structural and molecular comparison of bacterial and eukaryotic trigger factors.

TL;DR: It is shown that chloroplast trigger factor is mainly monomeric and displays only moderate stability against thermal unfolding even under mild heat-stress conditions, illustrating a remarkable evolutionary robustness of chaperone conformations across various kingdoms of life.

Identification of prokaryotic and eukaryotic signal peptides and prediction of their cleavage sites.

TL;DR: A new method for the identification of signal peptides and their cleavage sites based on neural networks trained on separate sets of prokaryotic and eukaryotic sequence that performs significantly better than previous prediction schemes and can easily be applied on genome-wide data sets.
