41Bcl-2 — is the prototype for a family of mammalian genes and the proteins they produce. They govern mitochondrial outer membrane permeabilization (MOMP) and can be either pro apoptotic (Bax, BAD, Bak and Bok among others) or anti apoptotic (including Bcl …
42Coiled coil — For the coiled coil shape in general, see Coil. Figure 1: The classic example of a coiled coil is the GCN4 leucine zipper (PDB accession code 1zik), which is a parallel, left handed homodimer. However, many other types of coiled coil exist. A… …
43Primordial sandwich — The concept of the primordial sandwich was proposed by the chemist Günter Wächtershäuser to describe the possible origins of the first cell membranes, and, therefore, the first cell.According to the two main models of abiogenesis, RNA world and… …

4614-3-3 protein — 14 3 3 proteins are a family of conserved regulatory molecules expressed in all eukaryotic cells. 14 3 3 proteins have the ability to bind a multitude of functionally diverse signaling proteins, including kinases, phosphatases, and transmembrane… …
47Apolipoprotein — Apolipoproteins are proteins that bind to fats (lipids). They form lipoproteins, which transport dietary fats through the bloodstream. Dietary fats are digested in the intestine and carried to the liver. Fats are also synthesized in the liver… …
48Fatty alcohol — Fatty alcohols are aliphatic alcohols derived from natural fats and oils, originating in plants, but also synthesized in animals and algae. Their significance in nutrition and health has historically been overlooked, and is only now being… …
49Beer head — The foam on top of beer is called a head. It is caused by bubbles of carbon dioxide rising to the surface. The carbon dioxide may be produced naturally by the activity of the brewers yeast, or artificially by dissolving carbon dioxide under… …
50Krüppel associated box — The Krüppel associated box (KRAB) domain is a category of transcriptional repression domains present in approximately 200 human zinc finger protein based transcription factors. The KRAB domain typically consists of about 75 amino acid residues… …
