Disease
[FA10_HUMAN] Defects in F10 are the cause of factor X deficiency (FA10D) [MIM:227600]. A hemorrhagic disease with variable presentation. Affected individuals can manifest prolonged nasal and mucosal hemorrhage, menorrhagia, hematuria, and occasionally hemarthrosis. Some patients do not have clinical bleeding diathesis.[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17]
Function
[FA10_HUMAN] Factor Xa is a vitamin K-dependent glycoprotein that converts prothrombin to thrombin in the presence of factor Va, calcium and phospholipid during blood clotting.
Publication Abstract from PubMed
More than just the sum of its parts: The superadditivity effect of fragment linking on DeltaG was quantified by deconstructing two fXa inhibitors with congeneric fragments, but different linkers. By connecting both fragments with a single bond, a high linker contribution DeltaG(link) of -14.0 kJ mol(-1) results, which corresponds to an improvement in affinity by around 2.5 orders of magnitude relative to the sum of fragment DeltaG values.
