A Pepsin-like Enzyme from Penicillium janthinellum

Journal of Biological Chemistry, 1968
Abstract The acid proteinase, peptidase A, of Penicillium janthinellum which shows many similarities to pepsin is completely inactivated by diazoacetyl-dl-norleucine methyl ester. One equivalent of inhibitor becomes covalently bound to 1 molecule of the enzyme.

Freeze-Dried Tuna Pepsin Powder Stabilized by Some Cryoprotectants: In Vitro Simulated Gastric Digestion toward Different Proteins and Its Storage Stability

Foods, 2022
The impact of maltodextrin (10%) in combination with trehalose or glycerol at different levels (2.5% and 5%) and their mixture on the stability of freeze-dried pepsin from skipjack tuna stomach was studied.

Protein acidification and hydrolysis by pepsin ensure efficient trypsin-catalyzed hydrolysis.

Food & Function, 2021
Enzyme-catalysed hydrolysis is important in protein digestion. Protein hydrolysis is initiated by pepsin at low pH in the stomach. However, pepsin action and acidification happen simultaneously to gastric emptying, especially for liquid meals. Therefore,

Diagnostic Value of Fasting and Bedtime Saliva Pepsin Measurements in Laryngopharyngeal Reflux

Biomedicines
Background: The pepsin test is an emerging non-invasive diagnostic approach for laryngopharyngeal reflux (LPR). The aim of this study was to investigate the diagnostic value of multiple salivary pepsin tests for detecting LPR.

Protease resistance of food proteins: a mixed picture for predicting allergenicity but a useful tool for assessing exposure

Clinical and Translational Allergy, 2018
Background Susceptibility to pepsin digestion of candidate transgene products is regarded an important parameter in the weight-of-evidence approach for allergenicity risk assessment of genetically modified crops.

Pepsin Promotes Activation of Epidermal Growth Factor Receptor and Downstream Oncogenic Pathways, at Slightly Acidic and Neutral pH, in Exposed Hypopharyngeal Cells

International Journal of Molecular Sciences, 2021
Pepsin refluxate is considered a risk factor for laryngopharyngeal carcinogenesis. Non-acidic pepsin was previously linked to an inflammatory and tumorigenic effect on laryngopharyngeal cells in vitro.

Antibacterial activity of a pepsin‐derived bovine hemoglobin fragment [PDF]

FEBS Letters, 2001
Peptic digestion of bovine hemoglobin yields a fragment with antibacterial activity. This peptide was purified to homogeneity by a two‐step procedure including anion exchange chromatography and preparative reversed‐phase HPLC. Mass determination and fragmentation indicated that this peptide corresponded to the 1–23 fragment of the α chain of hemoglobin.
