kallidin (bradykininogen)

Function

• precursor of bradykinin
• cleavage of N-terminal Lys by an aminopeptidase yields bradykinin
• Kallidin is formed from LMW kininogen

Structure

• undecapeptide (11 residues)
• differs from bradykinin by a single Lys at the amino terminus

More general terms

• kinin

Additional terms

• aminopeptidase
• bradykinin
• low molecular weight [LMW] kininogen (alpha-2 thiol proteinase inhibitor)
