Hydrogenase Mimic
A hydrogenase mimic or bio-mimetic is an enzyme mimic of hydrogenases. Bio-mimetic compounds inspired in hydrogenases One of the more interesting applications of hydrogenases is to produce hydrogen, due its capacity to catalyze its redox reaction: In the field of hydrogen production, the incorporation of chemical compounds in electrochemical devices to produce molecular hydrogen has been a topic of huge interest in the recent years due to the possibility of using hydrogen as a replacement of the fossil fuels as an energetic carrier. This approach of using materials inspired by natural models to do the same function as their natural counterparts is called bio-mimetic approach. Nowadays this approach has received a big impulse due to the availability of high-resolution crystal structures of several hydrogenases obtained with different techniques. The technical details of these hydrogenases are stored in electronic databases at disposition to who may be interested. This informati ...

Enzyme Mimic
Enzyme mimic (or Artificial enzyme) is a branch of biomimetic chemistry, which aims at imitating the function of natural enzymes. An enzyme mimic is a small molecule complex that models the molecular structure, spectroscopic properties, or reactivity of an enzyme, sometimes called bioinspired complexes.Stephen J. Lippard, Jeremy M. Berg, ''Principles of Bioinorganic Chemistry'', University Science Books, 1994, Overview Enzymes are biological catalysts: biopolymers that catalyze a Chemical reaction, reaction. Although a small number of natural enzymes are built from RNA–termed Ribozymes–most enzymes are proteins. Like any other protein, an enzyme is an amino acid polymer with added Cofactor (biochemistry), cofactors and other post-translational modifications. Often, most of the amino acid polymer is indirectly involved with the enzymes function, perhaps providing ancillary structure or connectivity, indirect activity regulation, or molecular identification of the enzyme.
