Chloroplast Proteins
After solubilization of stroma-freed chloroplasts with deoxycholate, the lipids and the detergent used are separated from the proteins by gel filtration. In this way not denatured pigment-containing protein preparations were obtained. The particles in fraction 1 exhibited a molecular weight of 600 000 and contained an average of 25 chlorophyll molecules. The circular dichroism spectrum showed e...
متن کاملTwo Chloroplast Proteins Suppress Drought Resistance by Affecting ROS Production in Guard Cells.
Chloroplast as the site for photosynthesis is an essential organelle in plants, but little is known about its role in stomatal regulation and drought resistance. In this study, we show that two chloroplastic proteins essential for thylakoid formation negatively regulate drought resistance in Arabidopsis (Arabidopsis thaliana). By screening a mutant pool with T-DNA insertions in nuclear genes en...
متن کاملTargeting Misfolded Proteins to Fight Neurodegenerative Diseases
With the assistance of proteins called chaperones, newly translated proteins fold into the three-dimensional shapes that are critical to their function. When proteins fold abnormally or become unstable, the consequences can be dire for cells, particularly neurons, which are exquisitely sensitive to the accumulation of misfolded proteins. Many neurodegenerative diseases, like Parkinson’s and Cre...
متن کاملEvolution of Chloroplast J Proteins
Hsp70 chaperones are involved in multiple biological processes and are recruited to specific processes by designated J domain-containing cochaperones, or J proteins. To understand the evolution and functions of chloroplast Hsp70s and J proteins, we identified the Arabidopsis chloroplast J protein constituency using a combination of genomic and proteomic database searches and individual protein ...
متن کاملAbscisic Acid Refines the Synthesis of Chloroplast Proteins in Maize (Zea mays) in Response to Drought and Light
To better understand abscisic acid (ABA) regulation of the synthesis of chloroplast proteins in maize (Zea mays L.) in response to drought and light, we compared leaf proteome differences between maize ABA-deficient mutant vp5 and corresponding wild-type Vp5 green and etiolated seedlings exposed to drought stress. Proteins extracted from the leaves of Vp5 and vp5 seedlings were used for two-dim...
