OBSOLETE. (Was not defined before being made obsolete).

OBSOLETE. An oxygen carrier found in a few groups of invertebrates, e.g. sipunculid worms, certain molluscs, and crustaceans.

Catalysis of the lipoylation of a protein in two steps: ATP + (R)-lipoate + a [lipoyl-carrier protein]-L-lysine = a [lipoyl-carrier protein]-N6-(lipoyl)lysine + AMP + diphosphate (overall reaction): (1) ATP + (R)-lipoate = lipoyl-AMP + diphosphate; (2) lipoyl-AMP + a [lipoyl-carrier protein]-L-lysine = a [lipoyl-carrier protein]-N6-(lipoyl)lysine + AMP.

Catalysis of the endohydrolysis of beta-1,4-linkages between N-acetyl-D-glucosamine and D-glucosamine residues in a partly acetylated chitosan.

OBSOLETE. Inhibition of proteinase by a mechanism involving a bait region which contains specific sites, cleavage of which induces a conformational change that results in trapping of the proteinase; following cleavage in the bait region a thiolester bond is hydrolyzed and mediates the covalent binding of the protein to the proteinase; subsequently epsilon-amino groups of the proteinase react with thiolester linkages in the inhibitor to form stable amide links; the entrapped proteinase can now only act on low molecular mass substrates.

The directed movement of poly(A)+ mRNA out of the nucleus into the cytoplasm.

Catalysis of the reaction: 4 R'C(R)SH + O2 = 2 R'C(R)S-S(R)CR' + 2 H2O2.

Catalysis of the formation of disulfide bridges in proteins using FAD as the electron acceptor.

OBSOLETE. A blue, copper-containing oxygen carrier present in many molluscs and arthropods.

The function of binding to a sigma factor and stopping, preventing or reducing the rate of its transcriptional activity.

OBSOLETE. The function of binding to a transcription factor and stopping, preventing or reducing the rate of its transcriptional activity.

Sigma factors act as the promoter specificity subunit of eubacterial and plant plastid multisubunit RNA polymerases, whose core subunit composition is often described as alpha(2)-beta-beta-prime. Although sigma does not bind DNA on its own, when combined with the core to form the holoenzyme, the sigma factor binds specifically to promoter elements. The sigma subunit is released once elongation begins.

OBSOLETE. Plays a role in regulating transcription initiation.

Catalysis of the random hydrolysis of (1->4)-beta-D-mannosidic linkages in mannans, galactomannans, glucomannans, and galactoglucomannans.

Catalysis of the reaction: 2 (2R)-3-phosphoglycerate + 2 H+ = CO2 + D-ribulose 1,5-bisphosphate + H2O.
