In this paper, we examine the frequency distribution of 64 codons over the coding and non-coding regions of 88 DNA from EMBL and GenBank database, using exponential fitting. Also, we regard 20 amino-acids as vocabulary, perform the same frequency analysis to the same database and show that...
Nucleotide sequencing revealed that both clones encode 317 amino acids containing the peptide sequences. The deduced amino acid sequences of the two differ only by 13 residues (96%) identity), whereas the nucleotide sequences are relatively divergent (81% identity in the coding regions). These ...
These genes encode polypeptides of 879, 459 and 345 amino acids, respectively, which are also disclosed and claimed. The genes are useful as DNA probes or, for preparing PCR primers. The polypeptides are useful in antigenic, immunological or vaccine compositions. The nucleotides can be expressed...
Well,amino acidsin food make up protein. When protein is digested it is once again broken down into specific amino acids, that are then selectively put together for different uses. These new proteins formed in the body are what make up most solid matter in the body: skin, eyes, heart, i...
In keeping with these results, mutation of Lys360, Val361, and Lys365 diminished strongly the DNA binding activity of hRARα as a homodimer or a heterodimer. Our results thus provide direct evidence for the differential involvement of basic, polar, or aromatic amino acids in the DNA binding,...
Amino acid - Reactions, Structure, Synthesis: Amino acids via their various chemical functionalities (carboxyls, amino, and R groups) can undergo numerous chemical reactions. However, two reactions (peptide bond and cysteine oxidation) are of particular
Assignment of functional amino acids around the active site of human DNA topoisomerase IIalpha. An expression library for active site mutants of human topoisomerase IIalpha (TOP2alpha) was constructed by replacing the sequence encoding residues 793-80... Y Okada,Y Ito,A Kikuchi,... - 《...
To solve the analogy "Nucleotides : DNA :: Amino acids : ", we need to identify the relationship between the first pair of terms and apply that relationship to the second pair.1. Identify the first pair: The first pair is "Nucl
Mycosporine-like amino acids (MAAs) are water-soluble molecules that absorb UV-A and UV-B radiation and disperse the energy as heat. MAAs show great diversity in their molecular structures, which exhibit a range of molecular weights spanning 188 to 1050 Daltons. MAAs are utilized in a wide ...
Sulfur-containing amino acids attenuate the development of liver fibrosis in rats through down-regulation of stellate cell activation In cultured stellate cells, l-cysteine and l-methionine suppressed the DNA synthesis and the expression of growth factor receptors, smooth muscle 伪-actin ...
