2. 1. Cryo-EM Studies of Macromolecular Complexes from Photosynthetic Organisms

   Author : Annemarie Perez Boerema; Alexey Amunts; Mei Li; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cryo-EM; membrane proteins; photosynthesis; translation; chloroplast; ribosome; photosystem I; protein structure; Biochemistry; biokemi;

   Abstract : Plants, algae, and cyanobacteria convert light energy into chemical energy through the process of photosynthesis, fueling the planet and making life as we know it possible. Photosystem I (PSI) is one of the main photosynthetic complexes, responsible for this process. READ MORE

4. 2. Structural characterisation of mitochondrial macromolecular complexes using cryo-EM : Mitoribosome biogenesis and respiratory chain supercomplex

   Author : Sorbhi Rathore; Martin Ott; Daniel Wilson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mitochondria; mitoribosome biogenesis; mitoribosome assembly factors; yeast respiratory supercomplexes; single particle electron cryo-microscopy; cryo-EM sample preparation; Biochemistry; biokemi;

   Abstract : Mitochondria, popularly known as powerhouse of the cell, contain specialised mitoribosomes that synthesise essential membrane proteins. These essential proteins are required to form enzyme complexes, which carry out the process of oxidative phosphorylation (OXPHOS). READ MORE

5. 3. Cryo-EM and Computational Biology of Macromolecular Complexes

   Author : Andrew Emmerich; Suparna Sanyal; Erik Lindahl; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

   Abstract : The ribosome is a large, ancient multicomponent macromolecular complex which is highly amenable to study by cryogenic electron microscopy (cryo-EM) and computation biology methods. This thesis delves into the structure of both prokaryotic and eukaryotic ribosomes in the context of determining a solution to emerging antimicrobial resistance. READ MORE

6. 4. Light’EM up! : structural characterization of light-driven membrane protein complexes by cryogenic electron microscopy

   Author : André Tomás Graça; Wolfgang P. Schröder; Johannes Messinger; Karina Persson; Werner Kühlbrandt; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 3D reconstruction; Arabidopsis thaliana; assembly; chlorophyll; cryo-EM; cyanobacteria; Deinococus radiodurans; electron; land plants; membrane protein complexes; Photosystem II; proton; single-particle analysis; S-Layer Deinoxanthin Binding Complex SDBC ; water.; Biochemistry; biokemi; biologisk kemi; biological chemistry;

   Abstract : Photosynthesis is probably the most important process for allowing life to develop into the diverse forms we see today. In this process, solar radiation is used to convert CO2 into biomass. From this process, we obtain oxygen to breathe, sources of food (plant biomass), and the potential for clean and sustainable energy. READ MORE

7. 5. Fast and reliable alignment and classification of biological macromolecules in electron microscopy images

   Author : Björn Forsberg; Erik Lindahl; Sriram Subramaniam; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cryo-EM; electron microscopy; GPU; parallel processing; protein structure; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

   Abstract : In the last century, immense progress has been made to charter and understand a wide range of biological phenomena. The origin of genetic inheritance was determined, showing that DNA holds genes that determine the architecture of proteins, utilized by the cell for most functions. READ MORE
