Kininogens. Kininogen . Prekinins . Prokinins . T-Kininogen . Thiostatin . Kininogen Cystatins . T Kininogen . Cystatins, Kininogen . Endogenous peptides present in most body fluids. Certain enzymes convert them to active KININS which are involved in inflammation, blood clotting, complement reactions, etc. Kininogens belong to the cystatin superfamily. They are cysteine proteinase inhibitors. HIGH-MOLECULAR-WEIGHT KININOGEN; (HMWK); is split by plasma kallikrein to produce BRADYKININ. LOW-MOLECULAR-WEIGHT KININOGEN; (LMWK); is split by tissue kallikrein to produce KALLIDIN. . 0.55
Thionins. Peptides, Thonin . Thonin Peptides . Antimicrobial peptides of 45-47 amino acids and typically with four disulfide bridges. They are found in PLANTS. Type-V thionins lack the C-terminal nonapeptide. This should not be confused with thionine. . 0.50
