Granule with a membranous, tubular internal structure, found primarily in mature neutrophil cells. Most are released into the extracellular fluid. Specific granules contain lactoferrin, lysozyme, vitamin B12 binding protein and elastase.

Catalysis of the reaction: Na+(out) + K+(out) + Cl-(out) = Na+(in) + K+(in) + Cl-(in).

Primary lysosomal granule found in neutrophil granulocytes. Contains a wide range of hydrolytic enzymes and is released into the extracellular fluid.

Specialized secretory vesicle found in the cells of adrenal glands and various other organs, which is concerned with the synthesis, storage, metabolism, and secretion of epinephrine and norepinephrine.

Enables the directed movement of organic anions into, out of, within or between cells. Organic anions are atoms or small molecules with a negative charge which contain carbon in covalent linkage.

The formation of a double membrane-bound structure, the autophagosome, that occurs when a specialized membrane sac, called the isolation membrane, starts to enclose a portion of the cytoplasm.

Catalysis of the reaction: formyl-L-methionyl peptide + H2O = formate + methionyl peptide.

Enables the directed movement of folic acid (pteroylglutamic acid) into, out of, within or between cells. Folic acid is widely distributed as a member of the vitamin B complex and is essential for the synthesis of purine and pyrimidines.

A membrane-bound, cytoplasmic secretory granule found in enzyme-secreting cells and visible by light microscopy. Contain zymogen, an inactive enzyme precursor, often of a digestive enzyme.

Interacting selectively with transfer RNA.

The outer membrane of a zymogen granule.

Enables the directed movement of ammonium into, out of, within or between cells. Ammonium is the cation NH4+ which is formed from N2 by root-nodule bacteria in leguminous plants and is an excretory product in ammonotelic animals.

regulation of mitochondrial membrane permeability

regulation of transport across mitochondrial membrane

Any process that modulates the frequency, rate or extent of the passage or uptake of molecules by the mitochondrial membrane.
