Protein Turnover and Amino Acid Catabolism

Dietary Protein Turnover:

Dietary Protein Turnover

Protein Turnover Rates Vary:

Protein Turnover Rates Vary Dependence of the half-lives of cytosolic yeast proteins on the nature of their amino-terminal residues

Ubiquitin Related Protein Degradation:

Ubiquitin Related Protein Degradation

Protein Ubiquitination:

Protein Ubiquitination Multiple Ubiquitins can be polymerized to each other.

What determines whether a protein will become ubiquinated?:
