The general properties of a molecule of an individual protein depend primarily upon the nature and number of the amino acid residues of which it is composed and upon the sequence in which they are arranged along
Based on an empirical relationship between the change in the water–accessible area upon folding and the molar mass of the polypeptide, and assuming that 60% of the interior of the folded protein molecules is made up of apolar amino acid residues2) , the compact globular structure of a ...
2.1.1 Characteristics and biogenesis Transfer RNAs are small, non-coding conserved RNA molecules and are the most abundant amongst ncRNAs [10,18]. They serve as a link between the nucleotide coding sequence of a mRNA molecule and the amino acid sequence of a polypeptide chain du...
Moreover, papain has demonstrated the ability to polymerize alkyl ester of L-tyrosine,36 L-glutamic acid,37 L-lysine,38 L-leucine and L-valine.39 In addition to the synthesis of homopolypeptide, copolymerization of amino acids is first achieved by papain using L-glutamic acid ester and ...

How does an amino acid become attached to a tRNA molecule? What mechanism ensures amino acids get attached to the correct tRNA? What is the structure of a protein that occurs when several polypeptide chains interact with each other? What is the relationship between a polypeptide ...
Herein is reported a fusion polypeptide according to formula (I): NH2—S2—X1—S1—COOH, wherein X1 comprises either a random amino acid sequence or an amino acid sequence derived from a first polypeptide, S2 and S1 are non-overlapping amino acid sequences derived from a second polypeptide,...
