molecular function |
| GO:0004866 | | endopeptidase inhibitor activity | | Stops, prevents or reduces the activity of an endopeptidase, any enzyme that hydrolyzes nonterminal peptide bonds in polypeptides. |
| GO:0004857 | | enzyme inhibitor activity | | Binds to and stops, prevents or reduces the activity of an enzyme. |
| GO:0008191 | | metalloendopeptidase inhibitor activity | | Stops, prevents or reduces the activity of metalloendopeptidases, enzymes that catalyze the hydrolysis of nonterminal peptide bonds in a polypeptide chain and contain a chelated metal ion at their active sites which is essential to their catalytic activity. |
| GO:0030414 | | peptidase inhibitor activity | | Stops, prevents or reduces the activity of a peptidase, any enzyme that catalyzes the hydrolysis peptide bonds. |
biological process |
| GO:0010951 | | negative regulation of endopeptidase activity | | Any process that decreases the frequency, rate or extent of endopeptidase activity, the endohydrolysis of peptide bonds within proteins. |
| GO:0010466 | | negative regulation of peptidase activity | | Any process that stops or reduces the rate of peptidase activity, the hydrolysis of peptide bonds within proteins. |
cellular component |
| GO:0030288 | | outer membrane-bounded periplasmic space | | The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin peptidoglycan layer (PGL), also referred to as a thin cell wall. |
| GO:0042597 | | periplasmic space | | The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria). |
