Catalysis bioinspired

The catalytic properties of Mn enzyme structural models are not limited to the natural substrates of the enzymes they mimic. One could classify this catalysis based upon the substrates as biological mimetic catalysis or biomimetic catalysis [175] and biologically inspired catalysis or bioinspired catalysis [176], Unlike biomimetic catalysis, its bioinspired counterpart capitalizes on nature s findings to change nonnatural substrates chemically and, perhaps, unravel novel chemistry. 

Addressed how improvements in bioinspired catalysis might be harnessed for improved energy systems.

The knowledge gained from the study of metaUoenzyme models is also applicable in the design of transition metal complexes as catalytsts for specific reactions. This approach has come to be known as biomimetic or bioinspired catalysis and continues to be a fruitful and expanding area of research. 

SFB Molecular Catalysts Structure and Functional Design, biological and bioinspired catalysis therefore formed one of the pillars of scientific activities. 

Progresses in the study of oxygenations with molecular oxygen partly described above show the expand of chemistry from biomimetic or bioinorganic chemistry to bioinspired catalysis. The use of non-iron and -copper complexes provides not only mechanistic insights into the enzymatic oxygenations as described in Chapters 4 and 6, but different... 

The cationic complex [CpFe(CO)2(THF)]BF4 (23) can also catalyze the proton reduction from trichloroacetic acid by formation of Fe-hydride species and may be considered as a bioinspired model of hydrogenases Fe-H Complexes in Catalysis ) [44]. This catalyst shows a low overvoltage (350 mV) for H2 evolution, but it is inactivated by dimerization to [CpFe(CO)2l2-... 

The first examples of the so-called supramolecular catalysis are based on bioinspired molecular recognition, which is an essential attribute of biochemical systems. Structures such as receptors, antibodies, and enzymes can all recognize a feature that is important for their specific functions, often in the presence of species of quite similar structure. The ability to discriminate depends exclusively on the structural properties of these biological macromolecules. Recent progress in bioor-ganic chemistry has shown that many of these functions can be incorporated into smaller, synthetically more accessible structures as model systems [27].

Rauchfuss concluded by restating his main point Synthesis enables translation of mechanistic insights into catalysis and is a critical component of the overall bioinspired effort. Even though redox chemistry and hydrogen seem quite old, the field is wide open for new discoveries. 

The design principles for the rational construction of light-driven coimterparts of bioinorganic, bio-organometallic, and bio-catal5rtic systems have recently been reviewed in more detail (5). Here, we will limit oiu- discussion on the most important aspects and advantages of photoreactive components in bioinspired energy conversion and catalysis. 

We will not discuss the recent applications of the coupled streptavidin-biotin motif in bioinspired asymmetric catalysis, as an entire chapter is dedicated to Artificial Metalloenzymes , written by Prof. Thomas Ward.
