Many substances are known to act as inhibitors of various stages of protein synthesis. Included among these are a number of antibiotics produced by one strain of microorganism and lethal to other strains of the same or a different species. Some of the best understood inhibitors of protein synthesis are listed in Table 22-10. Because the actions of many of [...]
Some of the most important types of membrane proteins are as follows: 1. Peripheral (Extrinsic) Proteins 2. Integral (Intrinsic) Proteins 3. Asymmetric Distribution of Membrane Proteins 4. Mobility of Membrane Proteins 5. Enzymatic Properties of Membrane Proteins 6. Isolation and Characterization of Membrane Proteins. 1. Peripheral (Extrinsic) Proteins: Peripheral or extrinsic membrane proteins are generally loosely attached to the membrane [...]
Ontogeny and Phylogeny of Hemoglobin: Functionally and structurally similar proteins exist in diverse animal and plant species. Many of these are believed to have a common evolutionary origin. The picture of protein evolution is probably clearest in the case of the hemoglobin’s, where it is possible to make accurate comparisons of hemoglobin structure in many different animal species. Moreover, in [...]
