Any process that activates or increases the rate, frequency or extent of the directed movement of a motile cell or organism in response to a specific chemical concentration gradient.

Catalysis of the reaction: 2 peroxide radical + 2 H+ = O2 + H2O2.

The formation from simpler components of ocellus pigments, any general or particular coloring matter in living organisms, found or utilized in the ocellus, a minute simple eye found in many invertebrates.

copper, zinc superoxide dismutase activity

A part of the respiratory chain, containing about 10 polypeptide subunits including four redox centers: cytochrome b/b6, cytochrome c1 and an 2Fe-2S cluster. Catalyzes the oxidation of ubiquinol by oxidized cytochrome c1.

Formation and development of the ocellus, a simple visual organ of insects.

Any process that modulates the frequency, rate or extent of the directed movement of a motile cell or organism towards a lower concentration in a concentration gradient of a specific chemical.

eye pigment granule organization and biogenesis

The assembly and arrangement of intracellular pigment storage granules in the eye. The majority of pigment granules are found in the pigment cells. Smaller numbers are found in other cell types including the photoreceptor cell.

positive regulation of negative chemotaxis

Any process that activates or increases the rate, frequency or extent of the directed movement of a motile cell or organism towards a lower concentration in a concentration gradient of a specific chemical.

A part of the respiratory chain, containing the 13 polypeptide subunits of cytochrome c oxidase, including cytochrome a and cytochrome a3. Catalyzes the oxidation of reduced cytochrome c by dioxygen (O2).

Catalysis of the reaction: ATP + thiamin = AMP + thiamin diphosphate.

Any process that modulates the frequency, rate or extent of the directed movement of a motile cell or organism towards a higher concentration in a concentration gradient of a specific chemical.

Catalysis of the reaction: 2-methyl-4-amino-5-hydroxymethylpyrimidine diphosphate + 4-4-methyl-5-(2-phosphonooxyethyl)-thiazole = diphosphate + thiamin monophosphate.
