abstract：:HK31 (S565-K595) has previously been shown to encompass the binding domain for plasma prekallikrein (PK) within domain 6 of high molecular weight kininogen (HK). The complementary binding domain for HK within PK is mapped to PK56 (F56-G86), in the apple 1 domain, and to PK266 (K266-C295), in the apple 4 domain. Isothe...
