Catalysis of the reaction: 1,2-dihydrovomilenine + NADP(+) = H(+) + NADPH + vomilenine.

The modification process that results in the conversion of lysine, carried by a specialized lysine-accepting tRNA (possessing a CUA anticodon), to pyrrolysine (a lysine with an amide linkage to a (4R,5R)-4-substituted pyrroline-5-carboxylate).

Catalysis of the reaction: 2-hydroxy-1,4-benzoquinone + 2 H(+) + NADH = benzene-1,2,4-triol + NAD(+).

Catalysis of the reaction: (3Z)-phycocyanobilin + oxidized ferredoxin = biliverdin IXa + reduced ferredoxin.

Catalysis of the reaction: L-tryptophan + O(2) = alpha,beta-didehydrotryptophan + H(2)O(2) + H(+).

Catalysis of the reaction: trimethylamine + 2 (ferricytochrome c)-subunit + H2O = trimethylamine-N-oxide + 2 (ferrocytochrome c)-subunit + 2 H+.

Catalysis of the reaction: NAD(P)+ + mycothiol = NAD(P)H + H+ + mycothione.

Catalysis of the reaction: acetoacetate + coenzyme M + NADP(+) = 2-oxopropyl-coenzyme M + CO(2) + NADPH.

Catalysis of the reaction: trichloroethene + chloride + acceptor = tetrachloroethene + reduced acceptor.

Modulates the activity of any of the phosphatidylinositol 3-kinases (PI3Ks). Regulatory subunits can link a PI3K catalytic subunit to upstream signaling events and help position the catalytic subunits close to their lipid substrates.

The increase in length of the aristal core. The arista is the terminal segment of the antenna and consists of a central core and a series of lateral extensions.

OBSOLETE. The terminal region of a polytene chromosome.

Combining with the peptide myosuppressin to initiate a change in cell activity.

The process that gives rise to the patterns of cell differentiation that will arise in the chitin-based adult cuticle. An example of this process is adult chitin-based cuticle pattern formation in Drosophila melanogaster.

The increase in length of the aristal laterals. The arista is the terminal segment of the antenna and consists of a central core and a series of lateral extensions.

Catalysis of the reaction: a L-amino acid + H2O + O2 = a 2-oxo acid + NH3 + hydrogen peroxide.

The modification process that results in the conversion of serine, carried by a specialized tRNA(ser) (which can read a UGA anticodon), to selenocysteine.

The cell fate determination process that results in a cell becoming capable of differentiating autonomously into an endoderm cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed.
