	:::ORGANELLE DB:::
		Organelle DB compiles protein localization data from organisms spanning the eukaryotic kingdom and presents an organized catalog of the known protein constituents of more than 50 organelles, subcellular structures, and protein complexes.
		In particular, Organelle DB is a central repository of yeast protein localization data, incorporating results from both previous and current (ongoing) large-scale studies of protein localization in Saccharomyces cerevisiae.
		In total, Organelle DB is a singular resource consolidating our knowledge of the protein composition of eukaryotic organelles and subcellular structures.

		Using a combination of biophysical and proteomic techniques, European and Japanese scientists examined quantitatively the relative ratios of the lipids and 180 or so proteins that adorn synaptic vesicles, the compartments that house and traffic neurotransmitters essential for brain function (Cell 2006, 127, 671).
		The "big surprise" was the overall density of protein on the membrane of these vesicles, says author Reinhard Jahn, a neurobiologist at Max Planck Institute for Biophysical Chemistry in Göttingen, Germany.
		The high abundance of SNARE proteins in synaptic vesicles could increase the speed of fusion and, consequently, synaptic transmission, Jahn says.

		Mitochondria and chloroplasts (a type of plastid) are membrane-bound organelles that convert energy from foodstuffs (mitochondria) or sunlight (chloroplasts) into forms that can be used by the cell.
		The organelles likely evolved from bacteria that were endocytosed more than one billion years ago.
		Although the organelles maintain their own genomes, many genes encoding mitochondrial and chloroplast proteins are found in the cell nucleus.

		Organelles: (1) nucleolus (2) nucleus (3) ribosome (4) vesicle (5) rough endoplasmic reticulum (ER) (6) Golgi apparatus (7) Cytoskeleton (8) smooth ER (9) mitochondria (10) vacuole (11) cytoplasm (12) lysosome (13) centrioles
		In cell biology, an organelle is one of several structures with specialized functions enclosed by a membrane, suspended in the cytosol of a eucaryotic cell.
		Organelles were historically identified through the use of microscopy, and were also identified through the use of cell fractionation.

	Organelle - EvoWiki (Site not responding. Last check: )
		Organelle as its suffix intimates is a term used to describe the 'little' organs within cells.
		Organelles are a feature of eukaryotic cells and the debate as to origin of such functional compartmentalization is a controversial part of evolutionary theory.
		However, uniquely among organelles, they contain their own DNA and one suggestion as to their origin is that early bacteria were subsumed inside the cells of another.

		Finding a self-contained organelle inside a prokaryote is a puzzle as it suggests that the evolution of cells - the basic building blocks of higher organisms - may have to be reconsidered.
		He says it is significant that the same organelle is found in the more complicated eukaryotes implying that it may have a common evolutionary origin for both types of cell.
		Because the organelle is not present in animal cells, it may be a useful target for chemotherapy for those diseases.

	Organelle's discovery challenges theory, could alter approach to disease treatment
		"The organelle we found in the bacterium Agrobacterium tumefaciens is practically identical to the organelle called acidocalcisome in unicellular eukaryotes," said Roberto Docampo, a professor of veterinary pathobiology in the College of Veterinary Medicine at the University of Illinois at Urbana-Champaign.
		He soon determined that a tiny granule in yeast, fungi and bacteria, thought to be for storage, was a fully operational organelle containing pyrophosphatase, a pump-like enzyme that allows proton transport.
		The existence of discrete organelles is a defining component of unicellular eukaryotes, which have membrane-bound nuclei and specialized structures in their cell boundaries.
