Catalysis of the reaction: L-ornithinium(1+) = N(5)-acetyl-L-ornithine.

Catalysis of the reaction: 1-deoxy-11-oxopentalenate + O2 + NADPH + H+ = pentalenolactone D + H2O + NADP.

Catalysis of the reaction: L-threo-sphinganine + NADP <=> H+ + NADPH + 3-dehydrosphinganinium(1+).

Catalysis of the reaction: beta-amyrin + 2 O2 + 2 NADPH + 2 H+ <=> 11-oxo-beta-amyrin + 3 H2O + 2 NADP.

Catalysis of the reaction: glutathionate + a poly gamma-glutamylcysteine-beta-alanine = glycine + a poly gamma-glutamylcysteine-beta-alanine.

A series of reactions, mediated by the intracellular serine/threonine kinase protein kinase B (also called AKT), which occurs as a result of a single trigger reaction or compound.

The process of transferring reducing equivalents from the cytosol into the mitochondria; NADH is used to synthesise malate in the cytosol; this compound is then transported into the mitochondria where it is converted to oxaloacetate using NADH, the oxaloacetate reacts with gluamate to form aspartate, and the aspartate then returns to the cytosol to complete the cycle.

Catalysis of the reaction: 2-oxoglutarate(2-) + O2 + 2 H+ <=> ethene + 3 carbon dioxide + H2O.

Catalysis of the reaction: malonyl-CoA(5-) + an L-cysteine-S-conjugate <=> coenzyme A + H+ + an N-malonyl-L-cysteine-S-conjugate.

Catalysis of the reaction: H2O + a glutathione-toxin conjugate <=> glycine + a [Glu-Cys]-S-conjugate.

Catalysis of the reaction: glutathionate + L-gamma-glutamyl-L-cysteinyl-beta-alaninate <=> gamma-Glu-Cys-gamma-Glu-Cys-beta-Ala + glycine.

OBSOLETE. Binding to a component on the surface of a eukaryotic cell.

Catalysis of the reaction: an 11-cis retinol-[cellular-retinol-binding-protein] + a phosphatidylcholine <=> a cellular-retinol-binding protein + an 11-cis-retinyl ester + a 1-lysophosphatidylcholine.
