21. The Phe only when the proline peptide bond is in the " trans " state. 22. HIV proteases catalyze the hydrolysis of peptide bonds with high sequence selectivity and catalytic proficiency. 23. The carboxylic acids and amines link to form peptide bonds , also known as amide groups. 24. In this case, one mechanism is release of any incorrect aminoacyl-tRNA before peptide bond formation. 25. One of these prolines, Pro 220, is involved in a " cis " peptide bond . 26. Additionally, LepA has an effect on peptide bond formation. 27. Carboxypeptidases are enzymes that hydrolyze C-terminal peptide bonds . 28. This stored energy provides the majority of the energy needed for peptide bond formation during translation. 29. The protein is involved in protein biosynthesis and promotes the formation of the first peptide bond . 30. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues.
