Oxybenzone or benzophenone-3 or BP-3 (trade names Milestab 9, Eusolex 4360, Escalol 567, KAHSCREEN BZ-3) is an organic compound belonging to the class of aromatic ketones known as benzophenones. It takes the form of pale-yellow crystals that are readily soluble in most organic solvents.
An electron transport chain (ETC [1]) is a series of protein complexes and other molecules which transfer electrons from electron donors to electron acceptors via redox reactions (both reduction and oxidation occurring simultaneously) and couples this electron transfer with the transfer of protons (H + ions) across a membrane.
Benzophenone is a naturally occurring organic compound with the formula (C 6 H 5) 2 CO, generally abbreviated Ph 2 CO. Benzophenone has been found in some fungi, fruits and plants, including grapes. [4] It is a white solid with a low melting point and rose-like odor [5] that is soluble in organic solvents. Benzophenone is the simplest ...
MnhC - 113 and 3; MnhD - 498 and 13; MnhE - 159 and 4; MnhF - 97 and 3; MnhG - 118 and 3; In view of the complexity of the system, large variation in subunit structure, and the homology with NDH family protein constituents, a complicated energy coupling mechanism, possibly involving a redox reaction, cannot be ruled out.
Cytochrome b is a protein found in the membranes of aerobic cells. In eukaryotic mitochondria (inner membrane) and in aerobic prokaryotes, cytochrome b is a component of respiratory chain complex III (EC 1.10.2.2) — also known as the bc1 complex or ubiquinol-cytochrome c reductase.
7.4.2.3 ABC-type mitochondrial protein-transporting ATPase The expected taxonomic range for this enzyme is: Eukaryota, Bacteria. A non-phosphorylated, non-ABC (ATP-binding cassette) ATPase involved in the transport of proteins or preproteins into mitochondria using the TIM (Translocase of the Inner Membrane) protein complex.
The acyl carrier protein (ACP) is a cofactor of both fatty acid and polyketide biosynthesis machinery. It is one of the most abundant proteins in cells of E. coli. [ 1 ] In both cases, the growing chain is bound to the ACP via a thioester derived from the distal thiol of a 4'- phosphopantetheine moiety.
Ferredoxins (from Latin ferrum: iron + redox, often abbreviated "fd") are iron–sulfur proteins that mediate electron transfer in a range of metabolic reactions. The term "ferredoxin" was coined by D.C. Wharton of the DuPont Co. and applied to the "iron protein" first purified in 1962 by Mortenson, Valentine, and Carnahan from the anaerobic bacterium Clostridium pasteurianum.
