S TUDIES of the chemical nature of prothrombin have indicated a glycoprotein structure.2 Data obtained on purified bovine prothrombin have shown the reducing sugar content to be approximately 5 per cent, based on a reference standard of galactose and mannose.35 Laki et al.5 reported a value of 6.5 per cent in terms of glucose, and 1.6 to 1.7 per cent hexosamine.

Studies on the formation of the prothrombin-converting complex.

1. It has been shown that factor V accelerates the rate of conversion of prothrombin into thrombin by activated factor X, and that this activity does not depend on the presence of phospholipid. 2. Although the mechanism by which factor V increases the rate of reaction is not clear, it seems unlikely that it is converted into an enzyme. 3. The rate of conversion of prothrombin by purified activa...
