Catalysis of the reaction: acetylcholine + H2O = choline + acetate.

Catalysis of the reaction: an orthophosphoric monoester + H2O = an alcohol + phosphate.

Catalysis of the reaction: citrate = cis-aconitate + H2O = isocitrate, i.e. the interconversion of citrate and isocitrate via the labile, enzyme-bound intermediate cis-aconitate. Water is removed from one part of the citrate molecule and added back to a different atom to form isocitrate.

The directed movement of a motile cell or organism in response to a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).

Catalysis of the reaction: acyl-CoA + acceptor = 2,3-dehydroacyl-CoA + reduced acceptor.

A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.

Any process that modulates the frequency, rate or extent of muscle contraction.

Catalysis of the reaction: acyl-CoA + O2 = trans-2,3-dehydroacyl-CoA + H2O2.

Catalysis of the reaction: an acyl phosphate + H2O = a carboxylate + phosphate.

A process leading to shortening and/or development of tension in smooth muscle tissue.

Interacting selectively with retinoids, any member of a class of isoprenoids that contain or are derived from four prenyl groups linked head-to-tail. Retinoids include retinol and retinal and structurally similar natural derivatives or synthetic compounds, but need not have vitamin A activity.

Catalysis of the reaction: AMP + diphosphate = adenine + 5-phospho-alpha-D-ribose 1-diphosphate.

The complete fully infectious extracellular virus particle.

Interacting selectively with fatty acids, aliphatic monocarboxylic acids liberated from naturally occurring fats and oils by hydrolysis.

Catalysis of the reaction: L-2-aminoadipate + 2-oxoglutarate = 2-oxoadipate + L-glutamate.

Interacting selectively with iron (Fe) ions.
