A change of shape or structure of the whole organism from one developmental stage to another, particularly the rapid post embryonic structural transformation from larval to adult form.

Interacting selectively with a lipid antigen.

The aggregation or adhesion of compatible mating types via complementary cell-cell interactions prior to the formation of irreversible cellular contacts during conjugation.

Catalysis of the reaction: 3-phospho-D-glyceroyl phosphate = 2,3-bisphospho-D-glycerate.

Any process that modulates the frequency, rate or extent of the metabolism of ecdysteroids, a group of polyhydroxylated ketosteroids which initiate post-embryonic development, including the metamorphosis of immature forms and the development of the reproductive system and the maturation of oocytes in adult females.

Interacting selectively with an endogenous cellular lipid antigen.

Catalysis of the reaction: (5Z,13E)-(15S)-9-alpha,11-alpha-epidioxy-15-hydroxyprosta-5,13-dienoate = (5Z,13E)-(15S)-11-alpha,15-dihydroxy-9-oxoprosta-5,13-dienoate.

The activity of binding to and activating specific cell surface receptors, thereby inducing a behavioral or physiological response(s) from a responding organism or cell that leads to the transfer or union of genetic material between organisms or cells. The mating pheromone can either be retained on the cell surface or secreted.

Catalysis of the reaction: 2,3-diphosphoglycerate + H2O = 3-phosphoglycerate + phosphate.

Interacting selectively with an exogenous lipid antigen (examples include microbial lipids and glycolipids).

Catalysis of the reaction: (5Z,13E)-(15S)-9-alpha,11-alpha,15-trihydroxyprosta-5,13-dienoate + NADP+ = (5Z,13E)-(15S)-11-alpha,15-dihydroxy-9-oxoprosta-5,13-dienoate + NADPH.

Catalysis of the reaction: S-adenosyl-L-methionine + phosphatidyl-N-methylethanolamine = S-adenosyl-L-homocysteine + phosphatidyl-N-dimethylethanolamine.

branched-chain amino acid aminotransferase activity

Catalysis of the reaction: L-leucine + 2-oxoglutarate = 4-methyl-2-oxopentanoate + L-glutamate.
