| + | == Disease == | ||
| + | [[http://www.uniprot.org/uniprot/KLKB1_HUMAN KLKB1_HUMAN]] Defects in KLKB1 are the cause of prekallikrein deficiency (PKK deficiency) [MIM:[http://omim.org/entry/612423 612423]]; also known as Fletcher factor deficiency. This disorder is a blood coagulation defect. | ||
| + | == Function == | ||
| + | [[http://www.uniprot.org/uniprot/KLKB1_HUMAN KLKB1_HUMAN]] The enzyme cleaves Lys-Arg and Arg-Ser bonds. It activates, in a reciprocal reaction, factor XII after its binding to a negatively charged surface. It also releases bradykinin from HMW kininogen and may also play a role in the renin-angiotensin system by converting prorenin into renin. | ||

| + | == Publication Abstract from PubMed == | ||
| + | A series of macrocyclic analogues were designed and synthesized based on the cocrystal structure of small molecule plasma kallikrein (pKal) inhibitor, 2, with the pKal protease domain. This led to the discovery of a potent macrocyclic pKal inhibitor 29, with an IC50 of 2 nM for one olefinic isomer and 42.3 nM for the other olefinic isomer. | ||
