Escherichia coli K-12 substr. MG1655 Gene-Ontology-Terms Class: GO:0008233 - peptidase activity

Synonyms: hydrolase, acting on peptide bonds, peptide hydrolase activity, protease activity, proteinase activity

Definition: Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid.

Parent Classes:
GO:0016787 - hydrolase activity

Child Classes:
GO:0070011 - peptidase activity, acting on L-amino acid peptides (92)
