Regulation of Cu delivery to chloroplast proteins
Plastocyanin is a copper (Cu)-requiring protein that functions in photosynthetic electron transport in the thylakoid lumen of plants. To allow plastocyanin maturation, Cu must first be transported into the chloroplast stroma by means of the PAA1/HMA6 transporter and then into the thylakoid lumen by the PAA2/HMA8 transporter. Recent evidence indicated that the chloroplast regulates Cu transport ...
متن کاملCopper Delivery to Chloroplast Proteins and its Regulation
Copper is required for photosynthesis in chloroplasts of plants because it is a cofactor of plastocyanin, an essential electron carrier in the thylakoid lumen. Other chloroplast copper proteins are copper/zinc superoxide dismutase and polyphenol oxidase, but these proteins seem to be dispensable under conditions of low copper supply when transcripts for these proteins undergo microRNA-mediated ...
متن کاملUS line-ups outperform UK line-ups
In the USA and the UK, many thousands of police suspects are identified by eyewitnesses every year. Unfortunately, many of those suspects are innocent, which becomes evident when they are exonerated by DNA testing, often after having been imprisoned for years. It is, therefore, imperative to use identification procedures that best enable eyewitnesses to discriminate innocent from guilty suspect...
متن کاملBirth Preparedness and Its Effect on Place of Delivery and Post-Natal Check-Ups in Nepal
INTRODUCTION AND RATIONALE Number of demographically laggard countries will forego MDGs 4 and 5, and Nepal is not an exception to it. International reports reveal that, lack of adequate birth preparedness is one of the greatest hurdles in achievement of MDG 4 and 5. However, lack of comprehensive evidence at country level in developing countries like Nepal is a hindrance for policy making. In t...
متن کاملUps delivery to the intermembrane space of mitochondria: a novel affinity-driven protein import pathway.
Mitochondria are comprised of two aqueous subcompartments: the matrix and the intermembrane space (IMS). Following their synthesis on cytosolic ribosomes, proteins destined to the matrix are threaded by N-terminal matrixtargeting sequences through TOM and TIM translocases in the outer and the inner membrane of the organelle. Proteins of the IMS often lack such presequences, and the principles m...
