    [Abstract]

    A number of molecules, such as secreted peptides, have been shown to mediate root-to-shoot signaling in response to various conditions. The xylem is a pathway for water and molecules that are translocated from roots to shoots. Therefore, collecting and analyzing xylem exudates is an efficient approach to study root-to-shoot long-distance

    Apoplastic Expression of CARD1-ecto Domain in Nicotiana benthamiana and Purification from the Apoplastic Fluids
    本氏烟草中 CARD1-ecto 结构域的质外体表达及质外体液的纯化
    作者:Nobuaki Ishihama, Anuphon Laohavisit, Kaori Takizawa and Ken Shirasu日期:04/20/2022,浏览量:1553,Q&A: 0
    [Abstract]

    The protein expression and purification process is an essential initial step for biochemical analysis of a protein of interest. Traditionally, heterologous protein expression systems (such as E. coli, yeast, insect cells, and cell-free) are employed for plant protein expression, although a plant expression system is often desirable for plant

    Proteoliposomes for Studying Lipid-protein Interactions in Membranes in vitro
    体外研究膜脂-蛋白相互作用的蛋白质脂质体
    作者:Helmut Kirchhoff日期:10/20/2021,浏览量:1426,Q&A: 0
    [Abstract]

    Lipids in biomembranes can control the structure and, therefore, the functionality of membrane-embedded protein complexes. Unraveling how the lipid composition determines the mode of operation of membrane proteins provides mechanistic insights into their functionality. We applied a proteoliposome technique for studying how proteins function in

    Solubilization Method for Isolation of Photosynthetic Mega- and Super-complexes from Conifer Thylakoids
    从针叶树类囊体中分离光合巨复合体和超复合体的增溶方法

    [Abstract]

    Photosynthesis is the main process by which sunlight is harvested and converted into chemical energy and has been a focal point of fundamental research in plant biology for decades. In higher plants, the process takes place in the thylakoid membranes where the two photosystems (PSI and PSII) are located. In the past few decades, the evolution of

    In vitro Reconstitution Assays of Arabidopsis 20S Proteasome
    拟南芥20S蛋白酶体的体外重组分析

    [Abstract]

    The majority of cellular proteins are degraded by the 26S proteasome in eukaryotes. However, intrinsically disordered proteins (IDPs), which contain large portions of unstructured regions and are inherently unstable, are degraded via the ubiquitin-independent 20S proteasome. Emerging evidence indicates that plant IDP homeostasis may also be

    Purification of Protein-complexes from the Cyanobacterium Synechocystis sp. PCC 6803 Using FLAG-affinity Chromatography
    Cyanobacterium Synechocystis sp. PCC 6803 中蛋白混合物的标记亲和层析纯化方法
    作者:Minna M. Koskela, Petra Skotnicová, Éva Kiss and Roman Sobotka日期:05/20/2020,浏览量:3745,Q&A: 0
    [Abstract] Exploring the structure and function of protein complexes requires their isolation in the native state–a task that is made challenging when studying labile and/or low abundant complexes. The difficulties in preparing membrane-protein complexes are especially notorious. The cyanobacterium Synechocystis sp. PCC 6803 is a widely used model ...
    Extraction and Purification of Laccases from Rice Stems
    水稻茎秆酶的提取与纯化
    作者:Chenna Swetha and P. V. Shivaprasad日期:04/05/2019,浏览量:5064,Q&A: 0
    [Abstract] Laccases are found in cell walls of plants in very low amounts. This protocol provides an efficient method to purify laccases from rice stems. The method involves three steps: 1) Isolation of total protein from rice stems using buffers with high salt concentration to extract protein from cell walls; 2) Purification of laccases using concanavalin-A ...
    Isolation of Thylakoid Membranes from the Cyanobacterium Synechocystis sp. PCC 6803 and Analysis of Their Photosynthetic Pigment-protein Complexes by Clear Native-PAGE
    从蓝藻集胞藻sp. PCC 6803中分离类囊体膜并利用CN-PAGE非变性聚丙烯酰胺凝胶电泳分析光合色素蛋白复合物

    [Abstract] Cyanobacteria represent a frequently used model organism for the study of oxygenic photosynthesis. They belong to prokaryotic microorganisms but their photosynthetic apparatus is quite similar to that found in algal and plant chloroplasts. The key players in light reactions of photosynthesis are Photosystem I and Photosystem II complexes (PSI and ...
    Separation of Thylakoid Protein Complexes with Two-dimensional Native-PAGE
    采用二维非变性PAGE分离类囊体蛋白复合物
    作者:Marjaana Rantala, Virpi Paakkarinen and Eva-Mari Aro日期:07/05/2018,浏览量:8402,Q&A: 0
    [Abstract] The hierarchical composition and interactions of the labile thylakoid protein complexes can be assessed by sequential 2D-native gel-electrophoresis system. Mild non-ionic detergent digitonin is used to solubilize labile protein super-and megacomplexes, which are then separated with first-dimension blue native polyacrylamide gel electrophoresis ...
    Investigating Localization of Chimeric Transporter Proteins within Chloroplasts of Arabidopsis thaliana
    拟南芥叶绿体内嵌合转运蛋白的定位研究
    作者:Susumu Uehara, Yasuko Ito-Inaba and Takehito Inaba日期:02/05/2018,浏览量:8457,Q&A: 0
    [Abstract] In this protocol, we describe a method to design chimeric proteins for specific targeting to the inner envelope membrane (IEM) of Arabidopsis chloroplasts and the confirmation of their localization by biochemical analysis. Specific targeting to the chloroplast IEM can be achieved by fusing the protein of interest with a transit peptide ...
