In chemistry, an α-amino acid consists of an amino group, a carboxyl group, an R-group, and a hydrogen atom which is bonded to the α-carbon. The R-group represents a side chain specific to each amino acid and 20 different kinds of side chains (varying in shape, size, charge, ...
Translation termination is the process in protein synthesis where stop codons provide different levels of meaning, ranging from normal termination to regulated recoding. It involves the insertion of specific amino acids by near-cognate aa-tRNAs, which can lead to the suppression of premature termination...
Amino acids are linked by___between α-carboxyl andα-amino groups. The resulting polypeptide sequence has an___and a___. Section C Hybridization: The renaturation of complementary sequences between different nucleic acid molecules. Nucleosides:A nucleoside consists of a base covale...
Consists of at least one biologically- active agent; (b) at least one carrier comprising an acylated aldehyde of an amino acid, an acylated ketone of an amino acid, an acylated aldehyde of a peptide, an acylated ketone of a peptide
Like other mucins, submaxillary mucins have an amino acid domain rich in serine and threonine that forms a bridge with the hydroxyl groups of the N-acetylgalactosamine residues of the carbohydrate fraction.11,12 The carbohydrate region consists of up to five different monosaccharides, such as sialic...
The P38 benchmark set includes a series of alkyl amino substitutions originally investigated as part of a structure-activity relationship study into kinase inhibitors61. Here, the added amino group is correctly positioned to form a hydrogen bond with the protein backbone, though the i-Pr group is...
In ARB, amino acid sequences were derived from nucleotide sequences using the Translate DNA to Protein function and the standard genetic code. Because some arsC genes were incomplete, all three possible reading frames were examined to ensure correct translation. Amino acid sequences of the confirmed...
Glycine consists of a single carbon molecule attached to an amino and a carboxyl group. Its small size helps it to function as a flexible link in proteins and allows for the formation of helices, an extracellular signaling molecule, recognition sites on cell membranes and enzymes, a modifier ...
8.6.5.4The Structure of Phycobiliproteins All four of the phycobiliproteins described previously have been crystallized and their structures solved to atomic resolution.52The basic structure of a phycobiliprotein consists of a trimer of αβ paired subunits composed of nine linked α helices (Figure...
All known alanine racemases utilize pyridoxal 5′-phosphate as a cofactor, which forms animinelinkage with the α-amino group of alanine, hence increasing the acidity of the α-proton.Deprotonationof either alanineenantiomercould proceed via a two-base mechanism, with onebasepositioned on either side...
