Hydrogenase - Vincent Callebaut
Airships that produce biofuel from seaweed. The floating organic farm is a true organic purifying station composed of 4 carbon wells in which the green seaweeds recycle our carbonated waste brought by ships. This is directly dedicated to feed organically in biohydrogen the proactive airship.
Brief Introduction to Hydrogenase Enzyme
Molecular Hydrogen Synthesis
The word Hydrogenase identifies a class of enzymes that perform oxydation and redcution reactions on Hydrogen Molecule
Oxydation Reaction
$ H_2\text{aseAcceptor} $ identifies a Hydrogenase Enzyme ready to accept electrons
Reduction Reaction
$ H_2\text{aseDonor} $ identifies a Hydrogenase Enzyme ready to give electrons
Possible Applications
This class of enzymes attract a lot of attention because of their ability to produce molecular hydrogen reducing protons that could be generate as a photosynthesis byproduct.
Presenlty, the most common method to produce molecular hydrogen requires Platinum as a catalyzer but the abovementioned class of enzymes is interesting because of their higher efficiency in addition to the fact that the metals they're made of are Nickel and Iron that are much more earth-abundant.
A possibile application could be found here

The most interesting enzymes are [NiFe]-hydrogenase and [FeFe]-hydrogenase: the former shows a higher molecular hydrogen synthesis rate wrt to the latter but it is irreversibly damaged by the reaction with molecular oxygen while the latter is only temporarly inhibited.
The objective is thus to be able to design and synthesize a [FeFe]-hydrogenase variant O2 tolerant.

$ H_{ox} $ identifies the enzyme in its oxidative state while $ H_{red} $ identifies the enzyme in its reductive state.
The oxidation and reduction reaction take place at the distal Iron (the one with bound to the water molecule in the hydrogenase oxidative state).
Breve Introduzione all'Enzima Idrogenasi
Sintesi dell'Idrogeno Molecolare
Il termine Idrogenasi identifica una Classe di Enzimi che realizza reazioni di Ossidazione e Riduzione dell’Idrogeno descritte dalle seguenti reazioni
Ossidazione Idrogeno Molecolare
$ H_2\text{aseAcceptor} $ Indica un Enzima Idrogenasi accettore di elettroni e quindi in grado di ossidare la molecola di Idrogeno
Riduzione Protoni in Idrogeno Molecolare
$ H_2\text{aseDonor} $ Indica un Enzima Idrogenasi donatore di elettroni e quindi in grado di ridurre protoni e produrre una molecola di Idrogeno
Importanza applicativa dell’enzima idrogenasi
Il grande interesse per questo genere di enzimi deriva dalla loro capacità di produrre Idrogeno molecolare riducendo singoli protoni i quali si potrebbero ottenere come risultato della fotosintesi.
Il metodo attualmente più utilizzato si basa sull’impiego del Platino come catalizzatore per la reazione di riduzione protonica sopra citata, ma alcuni enzimi idrogenasi si stanno rivelando dei promettenti candidati alla sostituzione del platino per via della loro maggiore efficienza oltre al fatto che i metalli che compongono questi enzimi sono Nichel e Ferro i quali sono molto più abbondanti, sulla Terra, del Platino.
Si veda ad esempio

Gli enzimi di maggiore interesse sono [NiFe]Idrogenasi e [FeFe]Idrogenasi: il [FeFe]Idrogenasi ha un rendimento nella sintesi dell'idrogeno molecolare di molto superiore rispetto al [NiFe]Idrogenasi ma viene irrimediabilmente danneggiato dalla reazione con ossigeno molecolare mentre la funzionalità del secondo è solo parzialmente inibita.
L’obiettivo sarebbe quindi riuscire ad ottenere una variante del [FeFe]Idrogenasi tollerante al O2.

Il $ H_{ox} $ rappresenta (presumibilmente) l’enzima nel suo Stato Ossidante mentre il $ H_{red} $ rappresenta (presumibilmente) l’enzima nel suo Stato Riducente.
Le reazioni di ossidazione e riduzione avvengono probabilmente a livello del Ferro distale (quello sulla sinistra della proteina che, nel suo stato ossidante, presenta un legame con una molecola d’acqua)
