Prothrombin is activated on the surface of a phospholipid membrane where factor Xa removes the activation peptide and cleaves the remaining part into light and heavy chains. This domain corresponds to the light chain of thrombin.

This beta-sandwich is stabilised by six enclosed cysteines arranged in a [1-2, 3-5, 4-6] disulphide pairing resulting in a disulphide-rich hydrophobic core that is largely inaccessible to bulk solvent. The close proximity of disulfide bonds [3-5] and [4-6] organises haemadin into four distinct loops. The N-terminal segment of this domain binds to the active site of thrombin, inhibiting it [1].
