Transfer of Amino Acids from Aminoacyl-tRNAs to Proteins

Amino acids will be incorporated into proteins from the aminoacyl-tRNAs. To study this process we must acquire a wider knowledge of ribosomes and the messenger RNA, which will form a complex with the aminoacyl-tRNAs. Ribosomes: These are ribonucleoprotein particles consisting of about 65% RNAs and 35% proteins in the case of E.coli and which may be obtained from cellular homogenates [...]

Amino Acids and Formation of Aminoacyl-tRNAs | Biochemistry

In this article we will discuss about the activation of amino acids and formation of aminoacyl-tRNA. The first step of protein biosynthesis comprises two reactions (see fig. 6-43) catalyzed, for a given amino acid, by one and the same enzyme called activation enzyme, or aminoacyl-tRNA synthetase, or aminoacyl-tRNA ligase. In a first step, the L-amino acid is activated by ATP [...]
