Enzymatic activities of Maxilact

Food Chemistry, 1983
Nineteen enzymatic activities of Maxilact 20.000 have been assayed using the API ZYM micromethod. Some of them have been found to be positive and these have been studied in more detail. Hydrolysis of lactulose by the action of β-galactosidase is slower than that of lactose. Proteolytic activity has been found in both the soluble and insoluble fractions

On the enzymatic activity of albumin

Russian Journal of Bioorganic Chemistry, 2015
Albumin molecule, unlike molecules of many other plasma proteins, is not covered with carbohydrate shell. It plays a crucial role in maintaining of colloid osmotic pressure of the blood, and is able to bind and transport various endogenous and exogenous molecules.

Enzymatic Activity of Desquamin

Experimental Cell Research, 1994
We have previously described the properties of desquamin, a cell adhesion molecule in the stratum corneum with lectin-like properties specific for amino sugars. We report here that desquamin is also a trypsin-like serine proteinase. It degrades several chromogenic peptides with arginine in the P1 position, with greatest activity for the tissue ...

Non-enzymatic and enzymatic activation of mitomycin C: Identification of a unique cytosolic activity

International Journal of Cancer, 1996
Mitomycin C (MMC), an alkylating anti-tumor agent, was activated by non-enzymatic and enzymatic mechanisms leading to DNA binding and adduct formation. However, it was enzymatically, not non-enzymatically, activated MMC which induced inter-strand DNA cross-linking, a major determinant of cell death.

Sweetness and Enzymatic Activity of Lysozyme

Journal of Agricultural and Food Chemistry, 2001
Hen egg lysozyme elicits a sweet taste sensation for human beings. Effects of reduction of disulfide bonds, heat treatment, and chemical modification of hen egg lysozyme on both sweetness and hydrolytic activity were investigated. Both the sweetness and enzymatic activities were lost when the intradisulfide linkage in a lysozyme molecule was reduced ...

Presynaptic Neurotoxins with Enzymatic Activities

2008
Toxins that alter neurotransmitter release from nerve terminals are of considerable scientific and clinical importance. Many advances were recently made in the understanding of their molecular mechanisms of action and use in human therapy. Here, we focus on presynaptic neurotoxins, which are very potent inhibitors of the neurotransmitter release ...

D-Penicillamine and Enzymatic Activities

Enzyme, 2017
The influence of incubation with D-penicillamine on pure enzyme preparations and on enzymatic activities of serum and skin homogenates was investigated. Three of the nine enzymatic activities studied underwent significant changes. Such effects of D-penicillamine must be taken into consideration if therapeutic or unwanted actions of this drug are to be ...

HPLC assay of enzymatic activities

Chromatographia, 1987
Instead of traditional methods, high-performance liquid chromatography can be used for the determination of enzymatic activities. Assays can be performed once the reaction mixture have been injected in the HPLC apparatus. The elution of the samples is carried out with suitable buffers, and the product(s) formed and left oven substrate(s) are ...

Measuring Enzymatic Activities with Nanopores

ChemBioChem, 2020
AbstractNanopores have become powerful and versatile tools for measuring single molecules since their emergence in the mid‐1990s. They can be used to sense a wide variety of analytes including metal ions, small organic molecules, DNA/RNA, proteins, etc. to monitor chemical reactions, and to sequence DNA.

Pancreatin with High Enzymatic Activity*, †

Journal of the American Pharmaceutical Association (Scientific ed.), 1951
A simple method of preparing pancreatin with high lipase content is outlined. An analysis, by 50 independent workers, of the pancreatin prepared by this method shows that it contains also over three times the amount of trypsin and of amylase required by the U. S. P. Thus it is an easily prepared “triple strength” pancreatin of high lipase content.
