protein catabolic process (GO:0030163)

The chemical reactions and pathways resulting in the breakdown of a protein by the destruction of the native, active configuration with or without the hydrolysis of peptide bonds. Notes: - This term refers to the breakdown of mature proteins. For cleavage events involved in generating a mature protein from a precursor, consider instead the term 'protein maturation ; GO:0051604' and its children.
