The Milk-clotting Action of Papain*
Although the milk-clotting action of papain has been recognized for many years, this property of the enzyme has received little quantitative attention. It appears to be, however, a characteristic property of the proteolytic component of this enzyme system. Various workers have brought forth evidence as to the composite nature of the papain system, which has at least two components. In the most ...
متن کاملClotting of mammalian fibrinogens by papain: a re-examination.
Papain has long been known to cause the gelation of mammalian fibrinogens. It has also been reported that papain-fibrin is insoluble in dispersing solvents like strong urea or sodium bromide solutions, similar to what is observed with thrombin-generated clots in the presence of factor XIIIa and calcium. In those old studies, both the gelation and subsequent clot stabilization were attributed to...
متن کاملClotting activity of polyphosphate-functionalized silica nanoparticles.
We present a silica nanoparticle (SNP) functionalized with polyphosphate (polyP) that accelerates the natural clotting process of the body. SNPs initiate the contact pathway of the blood-clotting system; short-chain polyP accelerates the common pathway by the rapid formation of thrombin, which enhances the overall blood-clotting system, both by accelerating fibrin generation and by facilitating...
متن کاملAntibacterial Activity of Papain Hydrolysates of Buffalo Milk Whey Protein against Mastitis Pathogens
Mastitis, a severe infectious disease among dairy cattle, is still a challenge for livestock treatment due to the increased infections by antibiotic resistant strains. Antimicrobial peptides could be the alternate for treating such drug resistant strains. In the present study, the whey proteins extracted from buffalo milk was subjected to enzymatic hydrolysis using trypsin, chymotrypsin, pepsin...
متن کاملLoosely packed papain prosegment displays inhibitory activity.
Most protease prosegments are co-synthesized at the N-termini of cysteine proteases and are involved in folding assistance, inhibition, and activation of their mature enzymes. By using circular dichroism, UV-difference and fluorescence spectroscopies, we studied the thermal unfolding of papain prosegment. The transition seems to be two-state and reversible, with an unfolded state prone to aggre...
