Chloroplast targeting peptide是什么意思
WebJan 1, 2001 · The targeting of proteins within the confines of the chloroplast was first studied by Smeekens et al. (35). They demonstrated that plastocyanin was targeted into the chloroplast stroma by a typical transit peptide, but that a second signal, this time homologous to bacterial secretion peptides, directed the protein across the thylakoid … WebNov 22, 2024 · In the latter process, an N-terminal cleavable transit peptide serves as a targeting signal required for the import of nuclear-encoded chloroplast interior proteins. This import process is mediated via an interaction between the sequence motifs in transit peptides and the components of the TOC/TIC (translocon at the outer/inner envelope of ...

Novel machinery … WebJul 2, 2024 · We further fused and expressed the targeting peptides of AOXs with the mature form of PTOX in im individually; and found that targeting peptides of AOX1a, AOX1b, and AOX2, but not that of AOX1c or AOX1d, could direct PTOX into chloroplasts. It demonstrated that chloroplast-localized AOXs, but not mitochondria-localized AOXs, …
WebAbstract. Primary endosymbiosis, which gave rise to mitochondria or chloroplasts, required successful targeting of a number of proteins from the host cytosol to the endosymbiotic organelles. A survey of studies published in separate fields of biological research over the past 40 years argues for an antimicrobial origin of targeting peptides. WebDec 28, 2024 · Chloroplast-targeting peptide (CTP) delivers nucleic acids to chloroplasts of the leaf cell in a targeted way. The foliar spraying of siRNA or pDNA in complex with CTP and CPP (for cell penetration) results in translocation of these nucleic acids into the chloroplasts for engineering of organelle-specific genes.
