Abstract:
Sinomenine, an herbal ingredient isolated from Sinomenium acutum, is used for the amelioration of arthritis. It has been found that this molecule could bind to human serum transferrin (Tf), the iron (III) transport protein in the blood, by using fluorescence, circular dichroism (CD) spectroscopy, and molecular modeling methods. The results provide possible usage of transferrin to transport sinomenine.

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...
