Abstract:
The hemoglobin from the bacterium Vitreoscilla (VHb) is the first microbial hemoglobin that was conclusively identified as such (in 1986). It has been extensively studied with respect to its ligand binding properties and mechanisms, structure, biochemical functions, and the mechanisms by which its expression is controlled. In addition, cloning of its gene (vgb) into a variety of heterologous hosts has proved that its expression results substantial increases in production of a variety of useful products and ability to degrade potentially harmful compounds. Recent studies (since 2005) have added significant knowledge to all of these areas and shown the broad range of biotechnological applications in which VHb can have a positive effect.

Globular and Fibrous Proteins
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
