The catabolism of homologous and heterologous 7S gamma globulin fragments obtained by pepsin and papain digestion was studied in rabbits, guinea pigs, and mice. The elimination from the circulation of I* labeled gamma globulin fragments was followed and the urinary excretion of the total and protein-bound I* activity determined. Evidence is presented that the molecular structure responsible for...

OBJECTIVES This study aimed to evaluate the capacity of 2% chlorhexidine gel associated with 8% papain gel in comparison with 5.25% sodium hypochlorite in bovine pulp tissue dissolution. MATERIALS AND METHODS Ninety bovine pulps of standardized sizes were used and fragmented into 5-mm sizes. The fragments were removed from the root middle third region. They were divided into 6 experimental gr...

Buah pepaya merupakan buah yang tumbuh didaerah tropis rasanya enak dan banyak mengandung vitamin dibutuhkan oleh tubuh. Hampir semua bagian tanaman ini dapat dimanfaatkan seperti daun, bunga, batang getahnya. Getah berwarna putih cukup enzim pemecah protein (proteolitik) disebut papain, dimana mengkatalis ikatan menjadi senyawa-senyawa sederhana asam amino. Papain sebagai salah mempunyai beber...

Papain contains a cysteine-activatable proteinase that hydrolyzes benzoyll-arginlneamide (1). This enzyme has been shown to have a specificity similar to that of crystalline pancreatic trypsin (2) and therefore has been designated papain trypsinase (3). Previous experiments have shown that papain trypsinase exists in two inactive forms which can be designated papain-a-trypsinase and papain-13-t...

conclusions allicin vapor, or some decomposition product of allicin, causes inhibition of bacterial growth and biofilm formation. parallel enzymatic studies confirmed this inhibitory effect and suggest that sulfhydryl enzymes are involved in biofilm formation in the strain studied. results an inhibition effect was observed both in the bacterial cultures and the enzymatic solutions, and the exte...

The effects of papain protease and of vitamin A on explanted limb bone rudiments from 7- and 13-day chick embryos and fetal mice have been studied and compared. The incubation of cartilaginous rudiments from 7-day chick embryos in a solution containing papain and cysteine resulted in complete loss of the metachromasia of the cartilage matrix within 1 hour; explants treated in this fashion recov...

How the innate and adaptive immune systems cooperate in the natural history of allergic diseases has been largely unknown. Plant-derived allergen, papain, and mite allergens, Der f 1 and Der p 1, belong to the same family of cysteine proteases. We examined the role of protease allergens in the induction of Ab production and airway inflammation after repeated intranasal administration without ad...

The present studies were designed to determine the effect of papain upon IgM and IgD on the surface of murine splenocytes. By using radioiodinated cells, it was shown that IgD is more susceptible to cleavage by papain than IgM. The difference in susceptibility to papain of the two isotypes was not observed when cell lysates were employed, suggesting that attachment to the plasma membrane affect...

Background: Fungal keratitis is an acute or chronic inflammation of the cornea caused by fungi. The main treatment for fungal Natamycin 5%. Disadvantages natamycin are its poor penetration and increased resistance due to fungi which lower level ergosterol in wall. Purpose: Investigates effect bromelain, zingibain papain on LOX-1 receptors Aspergillus fumigatus. Result: receptor with bromelain p...

The structure of a recombinant pineapple cystatin (AcCYS) was determined by NMR with the RMSD of backbone and heavy atoms of twenty lowest energy structures of 0.56 and 1.11 Å, respectively. It reveals an unstructured N-terminal extension and a compact inhibitory domain comprising a four-stranded antiparallel β-sheet wrapped around a central α-helix. The three structural motifs (G(45), Q(89)XVX...
