Abstract:
This review focuses on recent progress in developing heterologous and recombinant expression as well as in vitro maturation systems for the biosynthesis of active [FeFe] and [NiFe]-hydrogenases, which catalyze the reversible reaction, H2 <--> 2e- + 2H+. Activities of [FeFe] and [NiFe]-hydrogenases produced from different recombinant and in vitro maturation approaches are compared. Examples of how hydrogenase expression supports basic and applied studies of these enzymes are presented, and barriers to achieving more viable biological and synthetic H2-production systems and catalysts are addressed.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
The hydrogenation process takes place on the surface of...
