Proteinase inhibitors in Brazilian leguminosae

open access: yesMemorias do Instituto Oswaldo Cruz, 1991
Serine proteinase inhitors, in the seeds of several Leguminosae from the Pantanal region (West Brazil), were studied using bovine trypsin, a digestive enzyme, Factor XIIa and human plasma Kallikrein, two blood clotting factors.

Dietary regulation of serine proteinases that are resistant to serine proteinase inhibitors

open access: yesJournal of Insect Physiology, 1997
Ingestion of Kunitz soybean trypsin inhibitor (STI) by larval Helicoverpa zea, Agrotis ipsilon, and Trichoplusia ni extended the retention time of food in the digestive tract and increased the level of activity of proteolytic enzymes that were not susceptible to inhibition by STI.

The effects of serine proteinase inhibitors on bone resorption in vitro [PDF]

open access: yesJournal of Endocrinology, 2003
Abstract The aims of this study were to identify the role and sites of action of serine proteinases (SPs) in bone resorption, a process which involves a cascade of events, the central step of which is the removal of bone matrix by osteoclasts (OCs).

TMPRSS2 as a Key Player in Viral Pathogenesis: Influenza and Coronaviruses

open access: yesBiomolecules
TMPRSS2, a human transmembrane protease enzyme, plays a crucial role in the spread of certain viruses, including influenza and coronaviruses. This enzyme promotes viral infection by cleaving viral glycoproteins, which helps viruses like SARS-CoV-2 and ...

Development of an in vitro cleavage assay system to examine vaccinia virus I7L cysteine proteinase activity

open access: yesVirology Journal, 2005
Through the use of transient expression assays and directed genetics, the vaccinia virus (VV) I7L gene product has been implicated as the major maturational proteinase required for viral core protein cleavage to occur during virion assembly.

Serine proteinases and their inhibitors in Phycomyces blakesleeanus.

open access: yesJournal of Biological Chemistry, 1979
Three serine proteinases of Phycomyces blakesleeanus were isolated and characterized. The molecular weights were determined to be 18,000, 22,000, and 60,000. The proteinases were solubilized by detergent or salt treatment. Two soluble proteins that specifically inhibit these proteinases were also isolated and characterized. Both these proteins formed 1:

The Search for Natural and Synthetic Inhibitors That Would Complement Antivenoms as Therapeutics for Snakebite Envenoming

open access: yesToxins, 2021
A global strategy, under the coordination of the World Health Organization, is being unfolded to reduce the impact of snakebite envenoming. One of the pillars of this strategy is to ensure safe and effective treatments.

Squash inhibitor family of serine proteinases.

open access: yesActa Biochimica Polonica, 1996
Squash inhibitors of serine proteinases form an uniform family of small proteins. They are built of 27-33 amino-acid residues and cross-linked with three disulfide bridges. The reactive site peptide bond (P1-P1') is between residue 5 (Lys, Arg or Leu) and 6 (always Ile). High resolution X-ray structures are available for two squash inhibitors complexed

The effects of a plant proteinase inhibitor from Enterolobium contortisiliquum on human tumor cell lines [PDF]

open access: yes, 2011
Supplementary to the efficient inhibition of trypsin, chymotrypsin, plasma kallikrein, and plasmin already described by the EcTI inhibitor from Enterolobium contortisiliquum, it also blocks human neutrophil elastase (K(iapp)=4.3 nM) and prevents phorbol ...
