Instances of dissimilarity occur primarily in the ability or inability to synthesize a particular amino acid. Thus, while plants, animals and microorganisms utilize generally the same amino acids for protein synthesis and other metabolic functions, they differ greatly in synthetic capacity. Whereas the ...
The discovery of glutamate synthase (NADPH-GOGAT, EC 1.4.1.13 and Fd-GOGAT, EC 1.4.7.1) in the 1970s gave rise to a new pathway of NH4+ assimilation into amino acids in concert with glutamine synthetase (GS, EC 6.3.1.2) (GS/GOGAT pathway). The subsequent studies led to an overall ...
Amino Acid Synthesis☆ L.Reitzer, inReference Module in Biomedical Sciences, 2014 Introduction The pathways ofamino acidsynthesis comprise a significant fraction of a bacterium's metabolic activity during growth in a minimal medium. Twoamino acids, glutamine andglutamate, are the immediate products of...
摘要 The discovery of glutamate synthase (NADPH-GOGAT, EC 1.4.1.13 and Fd-GOGAT, EC 1.4.7.1) in the 1970s gave rise to a new pathway of NH4+ assimilation into amino acids in concert with glutamine synthetase (GS, EC 6.3.1.2) (GS/GOGAT pathway). The subsequent studies led to an overa...
L-tryptophan, L-phenylalanine, and L-tyrosine are aromatic amino acids (AAAs) that are used for the synthesis of proteins and that in plants also serve as precursors of numerous natural products, such as pigments, alkaloids, hormones, and cell wall components. All three AAAs are derived from...
amino acid n. Any of various compounds containing an amino group (NH2), a carboxylic acid group (COOH), and a distinctive side chain, especially any of the 20 amino acids that link together to form proteins. Some amino acids (called nonessential) can be synthesized in the human body, whi...
Amino acid, any of a group of organic molecules that consist of a basic amino group, an acidic carboxyl group, and a unique organic side chain. The term amino acid is short for α-amino [alpha-amino] carboxylic acid. Examples of amino acids include glyci
Inconsistent results on the association between evolutionary rates and amino acid composition of proteins have been reported in eukaryotes. However, there are few studies of how amino acid composition can influence evolutionary rates in bacteria. Thus, we constructed linear regression models between compos...
