Activity of lactoperoxidase when adsorbed on protein layers.
Lactoperoxidase (LPO) is an enzyme, which is used as an antimicrobial agent in a number of applications, e.g., food technology. In the majority of applications LPO is added to a homogeneous product phase or immobilised on product surface. In the latter case, however, the measurements of LPO activity are seldom reported. In this paper we have assessed LPO enzymatic activity on bare and protein m...
متن کاملHuman salivary peroxidase and bovine lactoperoxidase are cross-reactive.
Peroxidases are abundant in nature, and the primary function of mammalian peroxidases is to catalyze the peroxidation of halides and pseudohalides. Previous studies have shown that antibodies raised against bovine lactoperoxidase moderately cross-react with human salivary peroxidase, a feature that has been used in the present study to examine epitopes common to the antigen and human salivary p...
متن کاملAn Important Milk Enzyme: Lactoperoxidase
It has been acknowledged since ancient times that milk and dairy products have a vital role in nutrition and contribute considerably to human health. Because of its content, Because of its content, it has many important effects on the life that include immuno‐ globulins, enzymes, hormones, growth factors, antibacterial agents, fat acids, vita‐ mins, and minerals. Approximately 70 indigenous enz...
متن کاملAntistreptococcal activity of lactoperoxidase.
A study of the inhibition of the growth of Streptococcus cremoris 972 by the enzyme lactoperoxidase has shown, in agreement with previous investigations, that the inhibition requires a source of both peroxide and thiocyanate. The thiocyanate may play more than one role. It stabilizes the very dilute solutions of lactoperoxidase employed in these studies, and its oxidation products may be involv...
متن کاملRole of porins in sensitivity of Escherichia coli to antibacterial activity of the lactoperoxidase enzyme system.
Lactoperoxidase is an enzyme that contributes to the antimicrobial defense in secretory fluids and that has attracted interest as a potential biopreservative for foods and other perishable products. Its antimicrobial activity is based on the formation of hypothiocyanate (OSCN-) from thiocyanate (SCN-), using H2O2 as an oxidant. To gain insight into the antibacterial mode of action of the lactop...
