Peptides

When a peptide bonds forms which of the following molecules is released?

In addition to the protein substrate a protease would require which additional molecule to perform catalysis?

If 3 moles of peptide bonds were formed how many grams of byproduct would be produced if the mole to mole ratio of peptide bond formed to byproduct produced is 1 to 1?

In the peptide sequence GAD the amino acid on the N-terminus is:

Scientists are attempting to track a peptide with a sequence of DFTGFI throughout a cell by attaching a fluorescent tag to its C-terminus. This means the fluorescent tag would directly attach to:

Scientists are attempting to immobilize a purified sample of peptide sequences to a positively charged binding medium maintained at physiological pH. If all of the amino acids within the peptides are classified as nonpolar then the scientists must be expecting:

Peptide bond formation occurs when an incoming amino acid’s amine group attacks:

Microproteins, proteins containing 60 amino acids or less, are difficult to visualize in vivo since the molecular weight and size of typical fluorescent tags typically interferes with the biophysical and biochemical features of microproteins. To solve this problem scientist developed single-residue terminal labeling (STELLA) tags that attach to the C-terminus of microproteins without interfering with normal functioning. Based on the information above which of the following functional groups within a STELLA tag allows it to attach to a microprotein regardless of the microprotein’s amino acid composition?

Peptide bonds contribute to the rigidity of proteins due to their:
