Background and Aim: The protease activity of fig latex has been reported in several articles. This study was carried out aiming at a comparison between proteases of the latex of Khorasan native fig tree and those of carica subspecies. Materials and Methods: In this experimental study, four latex proteases (Ficins) were extracted using salt fractionation and chromatography on Mono-S column (Ion...
The structure and function of snake venom proteases are briefly reviewed by putting the focus on their effects on hemostasis and thrombosis and comparing with their mammalian counterparts. Up to date, more than 150 different proteases have been isolated and about one third of them structurally characterized. Those proteases are classified into serine proteases and metalloproteinases. A number o...
Dupuytren's disease (DD) is a common fibrotic condition of the palmar fascia, leading to deposition of collagen-rich cords and progressive flexion of the fingers. The molecular mechanisms underlying the disease are poorly understood. We have previously shown altered expression of extracellular matrix-degrading proteases (matrix metalloproteases, MMPs, and 'a disintegrin and metalloprotease doma...
The complete amino acid sequences and the disulfide arrangements of the two chains of human haptoglobin 1-1 were established. The alpha 1 and beta chains of haptoglobin contain 83 and 245 residues, respectively. Comparison of the primary structure of haptoglobin with that of the chymotrypsinogen family of serine proteases revealed a significant degree of chemical similarity. The probability was...
BACKGROUND AND PURPOSE Focal cerebral ischemia causes microvessel matrix degradation and generates proteases known to degrade this matrix. However, proof that the proteases generated do indeed degrade vascular matrix is lacking. Here we demonstrate that active proteases derived from ischemic tissue after middle cerebral artery occlusion (MCAO) and transferred to normal tissue can degrade vascul...
