A protein kinase was located in the cytosol of pea mesophyll cells. The protein kinase phosphorylates, in an ATP-dependent manner, chloroplast-destined precursor proteins but not precursor proteins, which are located to plant mitochondria or plant peroxisomes. The phosphorylation occurs on either serine or threonine residues, depending on the precursor protein used. We demonstrate the specific phosphorylation of the precursor forms of the chloroplast stroma proteins ferredoxin (preFd), small… Expand
A Protein Kinase Family in Arabidopsis Phosphorylates Chloroplast Precursor Proteins*
TLDR
The protein kinases described here could represent subunits of a regulatory network involved in the cytosolic events of chloroplast protein import. Expand
Multiple Kinases Can Phosphorylate the N-Terminal Sequences of Mitochondrial Proteins in Arabidopsis thaliana
TLDR
The results suggested that the transit peptide of pSSU can compete with the presequences of pF1βs for an uncharacterized kinase(s) in leaf, and showed that phosphorylation of transit peptides/presequences are not uncommon for chloroplast- targeted and mitochondria-targeted proteins, albeit possibly differentially regulated.

Fidelity of targeting to chloroplasts is not affected by removal of the phosphorylation site from the transit peptide.
Phosphorylation of the transit peptide of several chloroplast-targeted proteins enables the binding of 14-3-3 proteins. The complex that forms, together with Hsp70, has been demonstrated to be anExpand
14-3-3 Proteins Form a Guidance Complex with Chloroplast
TLDR
It is concluded that the 14- 3-3-Hsp70-precursor protein complex is a bona fide intermediate in the in vivo protein import pathway in plants. Expand
Phosphorylation of chloroplast preproteins and the characterisation of nucleoside diphosphate kinase 2
TLDR
The present work shows that NDPK2 from Arabidopsis thaliana is also localised within the chloroplasts, which contradicts with earlier studies conducted with pea, spinach and Brassica campestris where this isoform was found to be in chloroplast. Expand
14-3-3 Proteins Form a Guidance Complex with Chloroplast Precursor Proteins in Plants
TLDR
The 14-3-3–Hsp70–precursor protein complex is a bona fide intermediate in the in vivo protein import pathway in plants and indicates an unrecognized selectivity of 14- 3-3 proteins for precursors from mitochondria and plastids in plants in comparison to fungi and animals. Expand
Toc, tic, and chloroplast protein import.
TLDR
Phylogenetic evidence suggests that several translocon subunits are of cyanobacterial origin, indicating that today's import machinery was built around a prokaryotic core. Expand
Effect of precursor protein phosphorylation on import into isolated chloroplasts from Chlamydomonas
TLDR
It is demonstrated that also in the green alga Chlamydomonas reinhardtii the precursor of the small subunit of ribulose‐1,5‐bisphosphate carboxylase becomes phosphorylated by a plant protein kinase and that the phosphorylation site is located in the transit peptide. Expand
The ACT domain in chloroplast precursor–phosphorylating STY kinases binds metabolites and allosterically regulates kinase activity
TLDR
It is found that isoleucine and S-adenosylmethionine bind to the ACT domain, negatively influencing its autophosphorylation ability and establishing that it has a role in binding amino acid ligands during chloroplast biogenesis. Expand
Phosphorylation and Dephosphorylation of the Presequence of Precursor MULTIPLE ORGANELLAR RNA EDITING FACTOR3 during Import into Mitochondria from Arabidopsis1[OPEN]
TLDR
The results suggest that Kinases, possibly STY kinases, and AtPAP2 are involved in the import of protein into both mitochondria and chloroplasts and provide a mechanism by which the Import of proteins into both organelles may be coordinated. Expand

Envelope membrane proteins that interact with chloroplastic precursor proteins.
TLDR
It is proposed that prSSU first binds in an ATP-independent fashion to the 86-kD protein, and the energy-requiring step is association with the 75- kD protein and assembly of a translocation contact site between the inner and outer membrane of the chloroplastic envelope. Expand
A constituent of the chloroplast import complex represents a new type of GTP-binding protein.
TLDR
Results indicate a possible regulatory function of OEP 34 in protein translocation into chloroplasts, and its GTP binding specificity is demonstrated by photo-affinity labelling in the presence of [alpha-32P]GTP. Expand
New Insights into the Protein Import Machinery of the Chloroplast's Outer Envelope
TLDR
A large number of plastid localized proteins are post-translationally imported as precursor proteins from the cytosol into the organelle, and proteins of the inner envelope membrane have been implied to function in the translocation event. Expand
Transit peptides of nuclear‐encoded chloroplast proteins share a common amino acid framework.
TLDR
It is proposed that these three shared sequence elements form a common framework in transit‐bearing chloroplast precursors which mediates the common functions performed by each transit peptide. Expand
Effect of mutations on the binding and translocation functions of a chloroplast transit peptide.
TLDR
It is found that at least the middle region and parts of the amino and the carboxyl termini of the transit peptide are more important for receptor binding than for translocation. Expand
Mitochondrial protein import.
TLDR
The transport of nuclear-encoded proteins from the cytosol into mitochondria is mediated by targeting (signal) sequences present on precursor forms, but the presence of a mitochondrial targeting sequence alone is not sufficient for specific targeting to the organelle and further to the various subcompartments. Expand
Protein Phosphorylation — Dephosphorylation in the Cytosol of Pea Mesophyll Cells
TLDR
It is proposed that the ratio of protein phosphorylation to protein dephosphorylation is regulated by the ATP to ADP ratio in the cytosol. Expand
Analysis of chloroplast transit peptide function using mutations in the carboxyl-terminal region
TLDR
The results show that removal of a conserved arginine residue in this region results in impaired processing, but does not necessarily affect import rates, and substituting amino acids with low reverse turn or amphiphilic potential for other original residues affected import rate but not processing. Expand
Translocation of proteins into isolated chloroplasts requires cytosolic factors to obtain import competence
TLDR
It is concluded that soluble proteins from outside the stromal compartment are necessary for post‐translational import of proteins into chloroplasts. Expand
Characterization of the protein import apparatus in isolated outer envelopes of chloroplasts
TLDR
A constitutively expressed homologue hsc 70 as part of a membrane complex which still contained the precursor protein and a second protein of 86 kDa molecular weight from the outer envelope membrane was also identified as a major component of this complex. Expand
