Any process that stops or reduces the rate of peptidase activity, the hydrolysis of peptide bonds within proteins.

Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism.

Any process that stops or reduces the rate of peptidase activity, the hydrolysis of peptide bonds within proteins.

An immune response against microbes mediated through a body fluid. Examples of this process are seen in the antimicrobial humoral response of Drosophila melanogaster and Mus musculus.

Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism.

The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of component monomers; protein oligomers may be composed of different or identical monomers. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer.

Any process that decreases the rate, frequency, or extent of the directed movement of calcium ions into a cell or organelle.

Any process that stops, prevents or reduces the frequency, rate or extent of flagellated sperm motility.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

The external part of the cell wall and/or plasma membrane.

A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.

A plasma membrane that is part of a sperm cell.

A structure in the head of a spermatozoon that contains acid hydrolases, and is concerned with the breakdown of the outer membrane of the ovum during fertilization. It lies just beneath the plasma membrane and is derived from the lysosome.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The external part of the cell wall and/or plasma membrane.

A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.
