Tyrosine is activated at an amino group with ATP to form tyrosyl adenylate.

Tyrosine is activated at an amino group with ATP to form tyrosyl adenylate. Correct Answer False

The above statement is false. Tyrosine is activated at the carboxyl group with ATP to form tyrosyl adenylate. The tyrosyl-tRNA synthetase catalyzes the charging of tRNATyr with tyrosine. Each amino acid has its specific tRNA to which it binds.

The peptide formation involves two amino acids covalently joined together between the carboxyl group of one amino acid and the amino group of another.
Analysis of a hexapeptide using enzymatic cleavage reveals the following result:
• Amino acid composition of the peptide is: 2R, A, V, S, Y
• Trypsin digestion yields two fragments and the compositions are: (R, A, V) and (R, S, Y)
• Chymotrypsin digestion yields two fragments and the compositions are: (A, R, V, Y) and (R, S)
• Digestion with carboxypeptidase A yields no cleavage product.
Given: Trypsin cleaves at carboxyl side of R. Chymotrypsin cleaves at carboxyl side of Y. Carboxypeptidase A cleaves at amino side of the C-terminal amino acid (except R and K) of the peptide.
The correct amino acid sequence of the peptide is:
