Catalysis of the reaction: ATP + 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxylate + L-aspartate = ADP + phosphate + (S)-2-(5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamido)succinate.

A chromosome found in the mitochondrion of a eukaryotic cell.

A gonadotrophic glycoprotein hormone secreted, in mammals, by the anterior pituitary gland.

The chemical reactions involving aromatic compounds, any organic compound characterized by one or more planar rings, each of which contains conjugated double bonds and delocalized pi electrons.

Splitting of a mitochondrion within a cell to form two or more separate mitochondrial compartments.

The formation from simpler components of eye pigments, any general or particular coloring matter in living organisms, found or utilized in the eye.

A generic term for parts of cells prepared by disruptive biochemical techniques.

Combining with gamma-aminobutyric acid (GABA, 4-aminobutyrate), an amino acid which acts as a neurotransmitter in some organisms, to initiate a change in cell activity.

Catalysis of the reaction: dopamine(out) + Na+(out) = dopamine(in) + Na+(in).

Interacting selectively with a peroxisomal targeting sequence, any of several sequences of amino acids within a protein that can act as a signal for the localization of the protein into the peroxisome.

Interacting selectively with retinal, one of the forms of vitamin A. Retinal plays an important role in the visual process in most vertebrates, combining with opsins to form visual pigments in the retina.

Catalysis of the hydrolysis of polypeptides, preferably at the first bond of Xaa-Arg-Lys, and less commonly at the first bond of Arg-Arg-Xaa, in which Xaa is not Arg or Lys.

The formation from simpler components of tetrahydrobiopterin, the reduced form of biopterin (2-amino-4-hydroxy-6-(1,2-dihydroxypropyl)-pteridine). It functions as a hydroxylation coenzyme, e.g. in the conversion of phenylalanine to tyrosine.

Catalysis of the reaction: gamma-aminobutyric acid(out) + Na+(out) = gamma-aminobutyric acid(in) + Na+(in).
