Organized structure of distinctive morphology and function, not bounded by a lipid bilayer membrane and occurring within the cell. Includes ribosomes, the cytoskeleton and chromosomes. An organelle found in the Cyanobacteria consisting of a proteinaceous coat and enzymes for the fixation of carbon dioxide including mechanisms for the concentration of carbonate to increase the efficiency of fixation under low-carbon dioxide conditions. An organelle found in bacteria consisting of a proteinaceous coat containing enzymes for the degradation of ethanolamine whose purpose is the protection of the rest of the cell from the toxic acetaldehyde product of the enzyme ethanolamine ammonia lyase. Organized structure of distinctive morphology and function, not bounded by a lipid bilayer membrane. Includes ribosomes, the cytoskeleton and chromosomes. An organelle found in bacteria consisting of a proteinaceous coat containing enzymes for the degradation of 1,2-propanediol whose purpose is the protection of the rest of the cell from the toxic propionaldehyde product of the enzyme diol dehydratase. Organized structure of distinctive morphology and function, occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton. Excludes the plasma membrane. An organelle found in bacteria consisting of a proteinaceous coat containing metabolic enzymes whose purpose is the sequestration or concentration of metabolites and which has the appearance of a polygonal granule by electron microscopy.
