Wikipedia
Kallidin is a bioactive kinin formed in response to injury from kininogen precursors through the action of kallikreins.
Kallidin is a decapeptide whose sequence is H-Lys-Arg-Pro-Pro-Gly-Phe-Ser-Pro-Phe-Arg-OH. It can be converted to bradykinin by the aminopeptidase enzyme.
It can be a substrate for carboxypeptidase M and N.
Kallidin is identical to bradykinin with an additional lysine residue added at the N-terminal end and signals through the bradykinin receptor.
Usage examples of "kallidin".
It exists in at least two separate and very similar varieties, called kaUidin I and kallidin II.
A substance similar to kallidin is produced in blood by the action of certain snake venoms.
Eventually, bradykinin, kallidin, and all similar hormones were grouped under the name kinins.
Bradykinin, for instance, turned out to be identical with kallidin I and to have a molecule made up of 9 amino acids.
