Complex that possesses NADH dehydrogenase (ubiquinone) activity.

positive regulation of positive chemotaxis

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

Any process that initiates the directed movement of a motile cell or organism towards a lower concentration in a concentration gradient of a specific chemical.

Catalysis of the transfer of an acetyl group to a nitrogen atom on the acceptor molecule.

sterol carrier protein X-related thiolase activity

Catalysis of the hydrolysis of a phosphodiester to give a phosphomonoester and a free hydroxyl group.

Catalysis of the reaction: a steryl ester + H2O = a sterol + a fatty acid.

Catalysis of the reaction: acyl-CoA + cholesterol = CoA + cholesterol ester.

The function that stimulates a cell to grow or proliferate. Most growth factors have other actions besides the induction of cell growth or proliferation.

detection of mechanical stimulus during sensory perception of sound

The series of events during the perception of sound in which a sensory mechanical stimulus is received and converted into a molecular signal. Sound is picked up in the form of vibrations.

Catalysis of the reaction: 3-beta-hydroxyandrost-5-en-17-one 3-sulfate + H2O = 3-beta-hydroxyandrost-5-en-17-one + SO4(2-) (sulfate).

detection of chemical stimulus during sensory perception of smell

The series of events during the perception of smell in which an olfactory chemical stimulus is received and converted into a molecular signal.

Catalysis of the reaction between succinate and CoA to form succinyl-CoA.

detection of chemical stimulus during sensory perception of taste

The series of events during the perception of taste in which a gustatory chemical stimulus is received and converted into a molecular signal.

Catalysis of the reaction: ATP + succinate + CoA = ADP + succinyl-CoA + phosphate.

light-activated voltage-gated calcium channel activity
