Answer to: The peptide bond is a) a hydrogen bond b) an ionic bond c) a covalent bond d) a bond between two monosaccharides e) None of the above By...
GIPC/POPC-(2)H31/β-sitosterol- and GIPC/POPC-(2)H31/stigmasterol-containing LUVs formed not only regular-shaped bilayer vesicles but also planar bilayer structures that seem more rigid and not able to bend and make proper vesicles (arrow in Fig. 8A). Download: Download high-res image (...
2. The N-terminal domain of HA2 is responsible for this second aggregation of HA ectodomains – it is a short amphiphilic N-terminal sequence that became known as the fusion peptide (FP). As with the first rosette of HA, this second rosette formation is considered a consequence...
(pH = 5.0), the side chains of His were protonated and positively charged aromatic His residues changed hydrogen bonding energies between the residues and prevented the formation of rigid β-sheets. Thus, the SAP adopted a random coil configuration. The stronger hydrophobic interactions provided...
The ten Frizzled receptors (FZDs) are essential in Wnt signaling and play important roles in embryonic development and tumorigenesis. Among these, FZD6 is closely associated with lens development. Understanding FZD activation mechanism is key to unlock t

Planar systems were treated as rigid bodies. For the following energy minimization processes, the structures were prepared as follows: except for the coordinating water, all water molecules were excluded from the model and protons and charges were added as described above. The ligand and protein ...
cleavage, tendency of many minerals to split along definite smooth planar surfaces determined by their crystal structure. The directions of these surfaces are related to weaknesses in the atomic structure of the mineral and are always parallel to a possible crystal face. The property of cleavage is...
1. A composition comprising: A) a peptide, wherein the peptide comprises the amino acid sequence GRKKRRQ-AibG-RPS (SEQ ID NO: 4), or a fragment or variant thereof; B) a peptide, wherein the peptide comprises the amino acid sequence GRKKRRQ-AibG-QRRKKRG (SEQ ID NO: 5), or a ...
A universal linker structure is provided, in which a functional group and activating leaving group are placed on a tether, allowing the placement of an electrophile at the end of an
