Chloroplast targeting peptide
WebChloroplast targeting peptides are cleaved off in the stroma by the Stromal Processing Peptidase, SPP. If the protein is further translocated to the thylakoid lumen, an additional thylakoid-transfer sequence is removed by the Thylakoidal Processing Peptidase, TPP.

WebJan 12, 2024 · FIGURE 1. Figure 1. Proteins targeting into thylakoid membranes through distinct pathways. The nuclear-encoded preprotein with an N-terminal transit peptide (TP) is translocated into the chloroplast stroma through the Toc/Tic system, and then the TP is cleaved by stromal processing peptidase. WebOct 1, 2000 · It is thought that two to three thousand different proteins are targeted to the chloroplast, and the ‘transit peptides’ that act as chloroplast targeting sequences are probably the largest class of targeting sequences in plants. At a primary structural level, transit peptide sequences are highly divergent in length, composition and organization.
WebJun 20, 2000 · Nuclear-encoded, chloroplast-destined proteins are synthesized with transit sequences that contain all information to get them inside the organelle. Different proteins are imported via a general protein import machinery, but their transit sequences do not share amino acid homology. Webtional targeting, we used FISH, immunofluorescence staining, and confocal microscopy to determine whether the mRNA is localized near the target compartment of the protein that it encodes. Cotranslational targeting requires translation to pro-duce a signal peptide, whereas mRNA-based targeting does not, because the localization signal is in the ...
WebApr 6, 2024 · To target proteins into chloroplasts, a transit peptide is necessary. The transit peptide is cleaved off during the import process at a specific site. However, the import efficiency of a transit peptide depends not only on the sequence motifs upstream of the cleavage site but also on those downstream from the cleavage site (Jeong et al. 2024 ). WebJul 12, 2024 · Abstract Reports on chloroplast-targeted protein delivery using cell-penetrating peptides are scarce. In this study, a novel peptide-based macromolecule delivery strategy targeting chloroplasts was successfully developed in wheat mesophyll protoplasts.
