Accepted name: Renilla-luciferin 2-monooxygenase
Reaction: Renilla luciferin + O2 = oxidized Renilla luciferin + CO2 + hν
For diagram click here
Glossary: Renilla luciferin = 2,8-dibenzyl-6-(4-hydroxyphenyl)imidazo[1,2-a]pyrazin-3(7H)-one
Other name(s): Renilla-type luciferase; aequorin; luciferase (Renilla luciferin)
Systematic name: Renilla-luciferin:oxygen 2-oxidoreductase (decarboxylating)
Comments: From the soft coral coelenterate Renilla reniformis. The luciferin is bound to a luciferin-binding protein (BP-LH2). The bioluminescent reaction between the luciferin complex, luciferase and oxygen is triggered by calcium ions. In vivo, the excited state luciferinluciferase complex undergoes the process of nonradiative energy transfer to an accessory protein, Renilla green fluorescent protein, which results in green bioluminescence. In vitro, Renilla luciferase emits blue light in the absence of any green fluorescent protein.

Accepted name: nitronate monooxygenase
Reaction: ethylnitronate + O2 = acetaldehyde + nitrite + other products
Other name(s): NMO; 2-nitropropane dioxygenase (incorrect)
Systematic name: nitronate:oxygen 2-oxidoreductase (nitrite-forming)
Comments: Previously classified as 2-nitropropane dioxygenase (EC 1.13.11.32), but it is now recognized that this was the result of the slow ionization of nitroalkanes to their nitronate (anionic) forms. The enzymes from the fungus Neurospora crassa and the yeast Williopsis saturnus var. mrakii (formerly classified as Hansenula mrakii) contain non-covalently bound FMN as the cofactor. Neither hydrogen peroxide nor superoxide were detected during enzyme turnover. Active towards linear alkyl nitronates of lengths between 2 and 6 carbon atoms and, with lower activity, towards propyl-2-nitronate. The enzyme from N. crassa can also utilize neutral nitroalkanes, but with lower activity.

Accepted name: dichloroarcyriaflavin A synthase
Reaction: dichlorochromopyrrolate + 4 O2 + 4 NADH + 4 H+ = dichloroarcyriaflavin A + 2 CO2 + 6 H2O + 4 NAD+
For diagram of reaction click here
Glossary: dichloro-arcyriaflavin A = rebeccamycin aglycone
Systematic name: dichlorochromopyrrolate,NADH:oxygen 2,5-oxidoreductase (dichloroarcyriaflavin A-forming)
Comments: The conversion of dichlorochromopyrrolate to dichloroarcyriaflavin A is a complex process that involves two enzyme components. RebP is an NAD-dependent cytochrome P450 oxygenase that performs an aryl-aryl bond formation yielding the six-ring indolocarbazole scaffold [1]. Along with RebC, a flavin-dependent hydroxylase, it also catalyses the oxidative decarboxylation of both carboxyl groups. The presence of RebC ensures that the only product is the rebeccamycin aglycone dichloroarcyriaflavin A [2]. The enzymes are similar, but not identical, to StaP and StaC, which are involved in the synthesis of staurosporine [3].

EC 1.13.12.19
Accepted name: 2-oxuglutarate dioxygenase (ethylene-forming)
Reaction: 2-oxoglutarate + O2 = ethylene + 3 CO2 + H2O
Other name(s): ethylene-forming enzyme; EFE
Systematic name: 2-oxuglutarate:oxygen oxidoreductase (decarboxylating, ethylene-forming)
Comments: This is one of two simultaneous reactions catalysed by the enzyme, which is responsible for ethylene production in bacteria of the Pseudomonas syringae group. In the other reaction [EC 1.14.11.34, 2-oxoglutarate/L-arginine monooxygenase/decarboxylase (succinate-forming)] the enzyme catalyses the mono-oxygenation of both 2-oxoglutarate and L-arginine, forming succinate, carbon dioxide and L-hydroxyarginine, which is subsequently cleaved into guanidine and (S)-1-pyrroline-5-carboxylate. The enzymes catalyse two cycles of the ethylene-forming reaction for each cycle of the succinate-forming reaction, so that the stoichiometry of the products ethylene and succinate is 2:1.

Accepted name: leucocyanidin oxygenase
Reaction: leucocyanidin + 2-oxoglutarate + O2 = cis- and trans-dihydroquercetins + succinate + CO2 + 2 H2O
For diagram click here
Other name(s): anthocyanidin synthase
Systematic name: leucocyanidin,2-oxoglutarate:oxygen oxidoreductase
Comments: The enzyme requires Fe(II) and ascorbate. It is involved in the pathway by which many flowering plants make anthocyanin (glycosylated anthocyandin) flower pigments. The intermediates are transformed into cis- and trans-dihydroquercetin [2], which the enzyme can also oxidize to quercetin. Acidification of the products gives anthocyanidin [1], which, however, may not be a natural precursor of the anthocyanins.

Glossary: red chlorophyll catabolite = RCC = (7S,8S,101R)-8-(2-carboxyethyl)-17-ethyl-19-formyl-101-(methoxycarbonyl)-3,7,13,18-tetramethyl-2-vinyl-8,23-dihydro-7H-10,12-ethanobiladiene-ab-1,102(21H)-dione
Other name(s): pheide a monooxygenase; pheide a oxygenase; PaO; PAO
Systematic name: pheophorbide-a,NADPH:oxygen oxidoreductase (biladiene-forming)
Comments: This enzyme catalyses a key reaction in chlorophyll degradation, which occurs during leaf senescence and fruit ripening in higher plants. The enzyme from Arabidopsis contains a Rieske-type iron-sulfur cluster [2] and requires reduced ferredoxin, which is generated either by NADPH through the pentose-phosphate pathway or by the action of photosystem I [4]. While still attached to this enzyme, the product is rapidly converted into primary fluorescent chlorophyll catabolite by the action of EC 1.3.1.80, red chlorophyll catabolite reductase [2,6]. Pheophorbide b acts as an inhibitor. In 18O2 labelling experiments, only the aldehyde oxygen is labelled, suggesting that the other oxygen atom may originate from H2O [1].

Accepted name: carbazole 1,9a-dioxygenase
Reaction: 9H-carbazole + NAD(P)H + H+ + O2 = 2'-aminobiphenyl-2,3-diol + NAD(P)+
Other name(s): CARDO
Systematic name: 9H-carbazole,NAD(P)H:oxygen oxidoreductase (2,3-hydroxylating)
Comments: This enzyme catalyses the first reaction in the pathway of carbazole degradation. The enzyme attacks at the 1 and 9a positions of carbazle, resulting in the formation of a highly unstable hemiaminal intermediate that undergoes a spontaneous cleavage and rearomatization, resulting in 2'-aminobiphenyl-2,3-diol. In most bacteria the enzyme is a complex composed of a terminal oxygenase, a ferredoxin, and a ferredoxin reductase. The terminal oxygenase component contains a nonheme iron centre and a Rieske [2Fe-2S] iron-sulfur cluster.
