(R) group for side chains that differ from each amino acid. Proteins are constitutional material of the human body and are the most abundant intracellularmacromolecules. According to their composition, proteins are classified into simple andcomplex proteins. Simple proteins are composed exclusively of ...
Nanostructures built from biomolecules such as proteins, DNA and RNA are attracting attention in many areas of biological and materials sciences. Such nanoscale engineering was pioneered with proteins, yet the use of DNA is rapidly gaining traction. What
In membranes composed of the non-bilayer lipid dielaidoyl-phosphatidylethanolamine, DSC studies revealed that, even at an extremely low protein:lipid molar ratio, HSP17 strongly stabilizes the lamellar liquid–crystalline phase at the expense of the non-lamellar lipid phase (HII) [66], which is...
The evolutions of some pivotal proteins in the central dogma may have originated from the well conserved small β-barrels within their core regions1. For example, the core domains of DNA polymerase D (PolD) from euryarchaea and all cellular RNA polymerases are composed of two homologous β-bar...
Signaling pathways allow cells to detect and respond to a wide variety of chemical (e.g. Ca2+ or chemokine proteins) and physical stimuli (e.g., sheer stress, light). Together, these pathways form an extensive communication network that regulates basic c
A statistical analysis shows that the aliphatic index, which is defined as the relative volume of a protein occupied by aliphatic side chains (alanine, valine, isoleucine, and leucine), of proteins of thermophilic bacteria is significantly higher than that of ordinary proteins. The index may be ...
all being composed of three intertwined polypeptide chains. In some collagens the chains are linked together bycovalent bonds, yielding a ropelike structure of greattensile strength. Indeed, the toughness ofleather, chemically treatedanimalskin, is due to its content of collagen. Elastin is also a...
2. Interaction of Silk Proteins with Metal Ions and the Factors Influencing the Interaction 2.1. Amino Acid Composition Bombyx mori L. silk is composed of SF and sericin, featuring an elliptical cross-section and a diameter of approximately 30 μm (Figure 1A). The SF contains two SF fibers,...
radiodurans due to simulated microgravity, however, it is unclear how the sheer stress and fluid convection associated with this method contributed to these changes and what the short-term effects of microgravity on this bacterium are. In the present study, parabolic flight was used to subject ...
The meaning of BENCE-JONES PROTEIN is a polypeptide composed of one or two antibody light chains that is found especially in the urine of persons affected with multiple myeloma.
