SF can be simplified to a high molecular weight amphiphilic copolymer that contains alternate hydrophobic and hydrophilic blocks or domains.17–19 The hydrophobic blocks consist of highly repetitive “glycine-alanine-glycine-alanine-serine” motifs that form anisotropic β-sheet nanocrystals, while the ...
The most common way to denote a primary structure is to write the amino acid sequence using the standard three-letter abbreviations for the amino acids. For example gly-gly-ser-ala is the primary structure for a polypeptide composed ofglycine, glycine,serine, andalanine, in that order, from ...
This work deals with the chemical composition, physical structure, and thermal behavior of Antheraea assama silk fibers. The amino acid composition is characterized by the high content of alanine, glycine, and serine. Among the amino acid residues with polar side chains, aspartic acid, arginine, ...
Group I amino acids areglycine,alanine,valine,leucine,isoleucine,proline,phenylalanine,methionine, andtryptophan. TheRgroups of these amino acids have eitheraliphaticoraromaticgroups. This makes them hydrophobic (“water fearing”). In aqueous solutions, globularproteinswill fold into a three-dimensional ...
The amino acids present in proteins differ from each other in the structure of their side (R) chains. The simplest amino acid isglycine, in whichRis a hydrogen atom. In a number of amino acids,Rrepresents straight or branchedcarbonchains. One of these amino acids isalanine, in whichRis th...
Threonine aldolases catalyze the pyridoxal phosphate (PLP) dependent cleavage of threonine into glycine and acetaldehyde and play a major role in the degradation of this amino acid. In nature, L- as well as D-specific enzymes have been identified, but the exact physiological function of D-threo...
To assess the role of the equivalent chamber-2 residue F114 in PaCGL, we replaced it with alanine or asparagine and compared the resulting variants with the wild type. The two mutations did not impair the overall structural properties as well as the tetrameric oligomerization of the purified ...

Thus, this part of the chain, which is rich in glycine and alanine residues (19 out of 43), seems to be disordered in the crystal. The packing interactions are very similar to those described by Ghosh et al. [31] for the protein alone. Neither the cofactor nor the substrate is ...
