Extracellular Pneumococcal Serine Proteases Affect Nasopharyngeal Colonization [PDF]

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
Streptococcus pneumoniae has evolved versatile strategies to colonize the nasopharynx of humans. Colonization is facilitated by direct interactions with host cell receptors or via binding to components of the extracellular matrix.

Serine Proteases in Rodent Hippocampus [PDF]

open access: yesJournal of Biological Chemistry, 1998
Brain serine proteases are implicated in developmental processes, synaptic plasticity, and in disorders including Alzheimer's disease. The spectrum of the major enzymes expressed in brain has not been established previously. We now present a systematic study of the serine proteases expressed in adult rat and mouse hippocampus.

Genome-wide survey of prokaryotic serine proteases: Analysis of distribution and domain architectures of five serine protease families in prokaryotes [PDF]

open access: yesBMC Genomics, 2008
Background Serine proteases are one of the most abundant groups of proteolytic enzymes found in all the kingdoms of life. While studies have established significant roles for many prokaryotic serine proteases in several physiological processes, such as ...

Modeling and structural analysis of PA clan serine proteases

open access: yesBMC Research Notes, 2012
Background Serine proteases account for over a third of all known proteolytic enzymes; they are involved in a variety of physiological processes and are classified into clans sharing structural homology. The PA clan of endopeptidases is the most abundant

REVIEW OF SERINE PROTEASE INHIBITORS: DEVELOPMENT AND APPLICATIONS [PDF]

open access: yesBulletin of Pharmaceutical Sciences. Assiut University, 2023
A class of enzymes known as proteases is responsible for catalyzing the breakdown of covalent peptide bonds. Proteases account for almost 2% of the genes in humans, infectious organisms, and other forms of life.

Peptidyl Activity-Based Probes for Imaging Serine Proteases

open access: yesFrontiers in Chemistry, 2021
Proteases catalyze the hydrolysis of peptide bonds. Products of this breakdown mediate signaling in an enormous number of biological processes. Serine proteases constitute the most numerous group of proteases, accounting for 40%, and they are prevalent ...

Comparative kinetic characterization of the activity of glycosylated and non-glycosylated trypsin-like serine protease isolated from adults of Rhyzopertha dominica (Coleoptera: Bostrichidae) reared on the grain of three different cultivars of wheat

open access: yesEuropean Journal of Entomology, 2023
Rhyzopertha dominica is a pest that uses trypsin-like serine protease enzymes to hydrolyse the proteins in the cereal grains on which it feeds. The present study reveals for the first time that that there are both glycosylated and non-glycosylated serine

Functional analysis of a missense mutation in the serine protease inhibitor SPINT2 associated with congenital sodium diarrhea. [PDF]

open access: yesPLoS ONE, 2014
Membrane-bound serine proteases play important roles in different biological processes. Their regulation by endogenous inhibitors is poorly understood.
