They are present in various proteins, primarily from bacteria, for example a BLUF domain is found at the N-terminus of the AppA protein from Rhodobacter sphaeroides.Canna Leaf Roller: Cannas are largely free of pests, but in the USA plants sometimes fall victim the Canna Leaf Roller, which can actually be two different insects. Larva of the Brazilian skipper butterfly (Calpodes ethlius), also known as the Larger Canna Leaf Roller, cut the leaves and roll them over to live inside while pupating and eating the leaf.Rhodopsin: Rhodopsin (also known as visual purple) is a light-sensitive receptor protein. It is named after ancient Greek ῥόδον (rhódon) for “rose”, due to its pinkish color, and ὄψις (ópsis) for “sight”.Sensory rhodopsin IITrapped ion quantum computer: A trapped ion quantum computer is one proposed approach to a large-scale quantum computer. Ions, or charged atomic particles, can be confined and suspended in free space using electromagnetic fields.Laser-induced breakdown spectroscopy: Laser-induced breakdown spectroscopy (LIBS) is a type of atomic emission spectroscopy which uses a highly energetic laser pulse as the excitation source. The laser is focused to form a plasma, which atomizes and excites samples.AutofluorescenceHalobacterium: In taxonomy, Halobacterium is a genus of the Halobacteriaceae.See the NCBI webpage on Halobacterium.Outline of water: The following outline is provided as an overview of and topical guide to water:Spectrophotometry: In chemistry, spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.Allen, D.Photopigment: Photopigments are unstable pigments that undergo a chemical change when they absorb light. The term is generally applied to the non-protein chromophore moiety of photosensitive chromoproteins, such as the pigments involved in photosynthesis and photoreception.UVB-induced apoptosis: UVB-induced apoptosis is the programmed cell death of cells that become damaged by ultraviolet rays. This is notable in skin cells, to prevent melanoma.List of countries by carbon dioxide emissionsFlavin groupFlavoprotein: Flavoproteins are proteins that contain a nucleic acid derivative of riboflavin: the flavin adenine dinucleotide (FAD) or flavin mononucleotide (FMN).Photosystem IPlanktothrix: Planktothrix is a genus of filamentous cyanobacteria (often called blue-green algae). P.Carbon–carbon bond: A carbon–carbon bond is a covalent bond between two carbon atoms. The most common form is the single bond: a bond composed of two electrons, one from each of the two atoms.Orange carotenoid N-terminal domain: In molecular biology the orange carotenoid N-terminal domain is a protein domain found predominantly at the N-terminus of the Orange carotenoid protein (OCP), and is involved in non-covalent binding of a carotenoid chromophore. It is unique for being present in soluble proteins, whereas the vast majority of domains capable of binding carotenoids are intrinsic membrane proteins.Electron transfer: Electron transfer (ET) occurs when an electron moves from an atom or a chemical species (e.g.Proton emissionBurst kinetics: Burst kinetics is a form of enzyme kinetics that refers to an initial high velocity of enzymatic turnover when adding enzyme to substrate.
