Membrane Bound Organelle is an Organized structure of distinctive Morphology and function, bounded by a Single Or Double Lipid Bilayer Membrane and occurring within the Cell. Includes the Nucleus, Mitochondria, Plastids, Vacuoles, and Vesicles.

    • PMID 10361306: “The napEDABC locus coding for the periplasmic nitrate reductase of Thiosphaera pantotropha has been cloned and sequenced . The large and small subunits of the enzyme are coded by napA and napB . The sequence of NapA indicates that this protein binds the GMP-conjugated form of the molybdopterin cofactor .Cysteine-181 is proposed to ligate the molybdenum atom .It is inferred that the active site of the periplasmic nitrate reductase is structurally related to those of the molybdenum-dependent formate dehydrogenases and bacterial assimilatory nitrate reductases, but is distinct from that of the membrane-bound respiratory nitrate reductases .”

    • A biological membrane or biomembrane is an enclosing or separating amphipathic layer that acts as a barrier within or around a cell. It is, almost invariably, a lipid bilayer, composed of a double layer of lipid (usually phospholipid) molecules and proteins that may constitute close to 50% of membrane content. [1]
