Plant copper chaperones.
Copper chaperones, soluble copper-binding proteins, are essential for ensuring proper distribution of copper to cellular compartments and to proteins requiring copper prosthetic groups. They are found in all eukaryotic organisms. Orthologues of the three copper chaperones characterized in yeast, ATX1, CCS and COX17, are present in Arabidopsis thaliana. Plants are faced with unique challenges to...
متن کاملDelivering copper within plant cells.
Two genes recently identified in Arabidopsis thaliana may be involved in sequestering free copper ions in the cytoplasm and delivering copper to post-Golgi vesicles. The genes COPPER CHAPERONE and RESPONSIVE TO ANTAGONIST1 are homologous to copper-trafficking genes from yeast and humans. This plant copper-delivery pathway is required to create functional ethylene receptors. The pathway may also...
متن کاملLow-stress transfer bonding using floatation
A novel method for transferring thin, large-area polymer layers from a mould and its subsequent bonding to a destination substrate is presented here. Buoyancy is used for transfer via floatation to allow the release of internal stress in the polymer and to avoid induced strain. Additionally, floatation leads to wrinkle-free contact between the polymer layer and its destination substrate, an imp...
متن کاملCapillarity and Archimedes’ Principle of Floatation
We consider some of the complications that arise in attempting to generalize a version of Archimedes’ principle of floatation to account for capillary effects. The main result provides a means to relate the floating position (depth in the liquid) of a symmetrically floating sphere in terms of readily observable geometric quantities. A similar result is obtained for an idealized case correspondi...
متن کاملCopper cofactor delivery in plant cells.
Copper (Cu) is a micronutrient that has roles in photosynthesis, respiration, antioxidant activity, cell wall metabolism and hormone perception. Excess Cu is toxic and therefore its delivery has to be tightly regulated. Recent progress in the study of Cu homeostasis has revealed not only components of the Cu delivery machinery but also regulatory systems that control Cu-protein expression and c...
