A series of 1,3,6-trisubstituted 1,4-diazepan-7-ones were prepared as kallikrein 7 (KLK7, stratum corneum chymotryptic enzyme) inhibitors. Previously reported compounds 1-3 were potent human KLK7 inhibitors; however, they did not exhibit inhibitory activity against mouse KLK7. Comparison of the human and mouse KLK7 structures reveals the cause of t...

BackgroundChemerin is a chemoattractant involved in immunity that also functions as an adipokine. Chemerin is secreted as an inactive precursor (chem163S), and its activation requires proteolytic cleavages at its C-terminus, involving proteases in coagulation, fibrinolysis, and inflammation. Previously, we found chem158K was the dominant chemerin f...

Termitomyces is a genus of edible mushrooms commonly consumed in Africa and Asia among the mushrooms collected from the wild. Termitomyces mushrooms grow as symbionts in the termite nests, where they produce various enzymes to help termites digest lignocellulosic substrates. Many species of Termitomyces are used by different ethnic groups with ethn...

BackgroundMesophilic alkaline serine proteases from various bacteria have been commercially applied in a range of industries owing to their high catalytic efficiency and wide substrate specificity. However, these proteases have an optimal catalytic temperature of approximately 50 °C, and their activity decreases significantly at low temperature. Th...

Vibrio parahaemolyticus, a Gram-negative bacterium, inhabits marine and estuarine environments and it is a major pathogen responsible globally for most cases of seafood-associated gastroenteritis in humans and acute hepatopancreatic necrosis syndrome in shrimps. There has been a dramatic worldwide increase in V. parahaemolyticus infections over the...

Trematodes, also known as flukes, are phylogenetically ancient parasitic organisms. Due to their importance as human and veterinary parasites, their proteins have been investigated extensively as drug and vaccine targets. Among those, proteases, as crucial enzymes for parasite survival, are considered candidate molecules for anti-parasitic interven...

Oligopeptidases are enzymes involved in the degradation of short peptides (generally less than 30 amino acids in size) which help pathogens evade the host defence mechanisms. Leptospira is a zoonotic pathogen and causes leptospirosis in mammals. Proteome analysis of Leptospira revealed the presence of oligopeptidase A (OpdA) among other membrane pr...

Legume species differ in whether or not the 7S globulins stored in seeds undergo proteolytic processing during seed development, while preserving the bicupin structure and trimeric assembly necessary for accumulation and packing into protein storage vacuoles. Two such cleavage sites have been documented for the vicilins in pea cotyledons: one in th...

Serpins are a broadly distributed superfamily of protease inhibitors that are present in all kingdoms of life. The acronym, serpin, is derived from their function as potent serine proteases inhibitors. Early studies of serpins focused on their functions in haemostasis since modulating serine proteases activities are essential for coagulation. Addit...

Serpins have a wide range of functions in regulation of serine proteases in the thrombotic cascade and in immune responses, representing up to 2-10% of circulating proteins in the blood. Selected serpins also have cross-class inhibitory actions for cysteine proteases in inflammasome and apoptosis pathways. The arterial and venous systems transport ...
