    Arabidopsis has three PsbQ-like (PQL) proteins in addition to the PsbQ subunit of the oxygen-evolving complex of PSII. Recent bioinformatic and proteomic studies suggested that the two PQL proteins, PQL1 (At1g14150) and PQL2 (At3g01440), might function in the chloroplast NAD(P)H dehydrogenase...

    Thylakoidal processing peptidase (TPP) is responsible for removing amino-terminal thylakoid-transfer signals from several proteins in the thylakoid lumen. Three TPP isoforms are encoded by the nuclear genome of Arabidopsis thaliana. Previous studies showed that one of them termed plastidic type...

    Most proteins required for chloroplast function are encoded in the nuclear genome and have to be translocated into the organelle upon synthesis on cytosolic ribosomes. The translocation is facilitated by a proteinaceous machinery located in the outer and inner chloroplast membrane, the Toc and...

    Successful import of hundreds of nucleus-encoded proteins is essential for chloroplast biogenesis. The import of cytosolic precursor proteins relies on the Toc- (translocon at the outer chloroplast membrane) and Tic- (translocon at the inner chloroplast membrane) complexes. In Arabidopsis...

    Chloroplast is a typical plant cell organelle where photosynthesis takes place. In this study, a total of 1 808 chloroplast core proteins in Arabidopsis thaliana were reliably identified by combining the results of previously published studies and our own predictions. We then constructed a...

    The article discusses a study which examines the in vivo subcellular localization of the FIS1A protein in transgenic Arabidopsis plants. The researchers observed that FIS1A associates with the membrane fraction of Arabidopsis leaf extracts and is present in different protein fractions. It also...

  • The extreme Albino3 (Alb3) C terminus is required for Alb3 stability and function in Arabidopsis thaliana. Urbischek, Manuela; Nick von Braun, Sabine; Brylok, Thomas; Gügel, Irene; Richter, Andreas; Koskela, Minna; Grimm, Bernhard; Mulo, Paula; Bölter, Bettina; Soll, Jürgen; Ankele, Elisabeth; Schwenkert, Serena // Planta;Sep2015, Vol. 242 Issue 3, p733 

    Main conclusion: The extreme Alb3 C terminus is important for Alb3 stability in a light dependent manner, but is dispensable for LHCP insertion or D1 synthesis. YidC/Oxa1/Alb3 dependent insertion of membrane proteins is evolutionary conserved among bacteria, mitochondria and chloroplasts....

    An auxilin-like J-domain-containing protein, JAC1, is necessary for chloroplast movement in Arabidopsis thaliana, to capture photosynthetic light efficiently under weak light conditions. Here, we performed crystallographic and functional analyses of the J-domain of JAC1. The crystal structure of...

    The PsbQ-like (PQL) proteins 1 and 2, previously shown to be located in the thylakoid lumen of Arabidopsis thaliana, are homologous to PSII oxygen-evolving complex protein PsbQ. Nevertheless, pql mutants showed no defects in PSII but instead the activity of the chloroplast NAD(P)H dehydrogenease...
