Function

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.

Supplementary info

Biological summary

Plasma Kallikrein 1B plays significant roles in the kinin-kallikrein system. Within this system it cleaves high-molecular-weight kininogen to release bradykinin a potent vasodilator. This enzyme is not part of a larger protein complex but operates independently to modulate various physiological responses. Plasma kallikrein's activity influences processes like pain vasodilation and inflammation making it important in homeostasis and acute-phase responses.

Mechanical summary

Plasma Kallikrein 1B also known as PKK or KLKB1 is a serine protease enzyme with an approximate mass of 88 kDa. It is important for the blood coagulation process. This protein is mainly expressed in the liver and circulates in the blood as the inactive precursor prekallikrein. Through cleavage prekallikrein converts into its active form plasma kallikrein. Plasma kallikrein exhibits various proteolytic activities influencing multiple substrates involved in hemostatic and inflammatory responses.

Pathway

Plasma Kallikrein 1B participates actively in the kallikrein-kinin and the contact activation pathways. In the kallikrein-kinin system it works alongside high-molecular-weight kininogen and factor XII which plays an important role in the intrinsic pathway of coagulation. Plasma kallikrein's enzymatic activities lead to the production of bradykinin and other peptides impacting blood pressure and inflammatory processes.

Disease

Plasma Kallikrein 1B associates strongly with hereditary angioedema and diabetic retinopathy. In hereditary angioedema its dysregulation leads to excessive bradykinin production causing episodes of swelling. In diabetic retinopathy elevated plasma kallikrein activity can exacerbate vascular complications. Plasma kallikrein's disorderly activities also connect it to other proteins like C1 inhibitor in these pathological conditions highlighting its importance in clinical studies.

    We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody.
    Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.
