A nuclear ubiquitin ligase complex that specifically targets SUMOylated proteins; the complex is formed of homodimers or heterodimers of RNF4 family ubiquitin ligases and is conserved in eukaryotes.

Catalysis of the reaction: pentane-2,4-dione + O2 = acetate + 2-oxopropanal.

OBSOLETE. Catalysis of the reaction: linoleate + O2 = (9Z,12Z)-(7S,8S)-dihydroxyoctadeca-9,12-dienoate.

The chemical reactions and pathways resulting in the formation of a peptidyl cysteine-peptidyl phenylalanine cross-link by the condensation of a cysteine thiol with the carbonyl of the preceding residue and alpha-beta dehydrogenation.

The chemical reactions and pathways resulting in the formation of a peptidyl serine-peptidyl glycine, or peptidyl cysteine-peptidyl glycine cross-link by the condensation of the serine hydroxyl or cysteine thiol with the carbonyl of the preceding residue and alpha-beta dehydrogenation.

Catalysis of the reaction: tryptophan + O2 = N-formylkynurenine. The product of the reaction depends on the substrate; D-tryptophan produces N-formyl-D-kynurenine, and L-tryptophan produces N-formyl-L-kynurenine.
