What it is Filled
The chemical reactions and pathways resulting in the breakdown of a protein by destruction of its native, active configuration, with or without hydrolysis of peptide bonds (Gene Ontology GO:0030163); in eukaryotes mainly through the ubiquitin-proteasome system and lysosomal or vacuolar pathways, and in bacteria through ATP-dependent proteases.
Why it exists Filled
Let an agent explain protein breakdown pathways, find Gene Ontology annotations, and relate protein degradation to physiology and disease with sources.
Distinguishing features Filled
- The ubiquitin-proteasome system degrades most short-lived proteins.
- Autophagy delivers proteins and organelles to lysosomes.
- Denaturation without hydrolysis also counts as catabolism in the GO definition.

- ER-associated degradation (ERAD)
- lysosomal, vacuolar and autophagic degradation
- organellar and bacterial protease degradation
