6 天之前 · ABSTRACT Chloroplasts, refined through more than a billion years of evolution in plants and algae, act as highly efficient and resilient converters of solar energy. ... of protein import and facilitates the seamless handover of precursor proteins from the TIC complex to the motor module via a structurally aligned interface.

2024年10月3日 · Chloroplast proteins are imported via the translocon at the outer chloroplast membrane (TOC)-translocon at the inner chloroplast membrane (TIC) supercomplex, driven by an ATPase motor. The Ycf2-FtsHi complex has been identified as the chloroplast import motor.

2023年5月8日 · Taking these observations together, we propose that the GLK1/2–BBX14/15/16 module provides a novel mechanism explaining how the chloroplast represses flowering to balance plant growth and reproductive development.

2020年8月1日 · Chloroplast functioning and efficient photosynthesis for plant growth rely on the metal cofactor-mediated electron transport chain, in particular the transition metals Fe, Mn, and Cu [1].

This novel approach of developing an organelle-focused plug-and-play module that standardizes the relatively conserved chloroplast metabolism, also allows for the fine-tuning of minor metabolic differences between different organisms containing a chloroplast.

2023年11月23日 · In this study, we developed a ubiquitin-based module (Nub–Cub) capable of directing interactions in vivo between two chloroplast proteins lacking native affinities. We applied this module to genetically modify thylakoid multiprotein complexes.

2024年4月30日 · In the chloroplasts of WT cells, BPG2 binds to pre-30S ribosomal particles within nucleoids through its interaction with RP uS10c via the C-terminal GTPase domain, which ensures efficient processing of pre-rRNA and the production of plastome-encoded proteins.

2019年10月29日 · Therefore, we propose that ABCI10 (as the ATPase A-subunit) and ABCI12 (as the membrane-intrinsic, energy-coupling T-subunit) are part of a novel, chloroplast envelope-localized, AAT energy-coupling module of a prokaryotic-type ECF transporter, most likely involved in metal ion uptake.

2024年10月3日 · The heterohexameric AAA+ ATPase motor module is tilted, potentially facilitating preprotein handover from the translocon at the inner chloroplast membrane (TIC) complex. Preprotein interacts with Ycf2-FtsHi and enhances its ATPase activity in vitro .

Photosynthetic cells contain special pigments that absorb light energy. Different pigments respond to different wavelengths of visible light. Chlorophyll, the primary pigment used in...
