Substrate specificity of honeydew melon protease D, a plant serine endopeptidase. [PDF]
The substrate specificity of honeydew melon (Cucumis melo var. inodorus Naud) protease D was studied by the use of synthetic substrates and oligopeptides derived from a protein hydrolyzate. The hydrolysis rates of succinyl-(L-Ala)1-3-p-nitroanilide (Suc-(Ala)1-3-pNA) the hydrolysis rate progressively rose in proportion to the increased chain length ...

Purification and biochemical characterization of a vacuolar serine endopeptidase induced by glucose starvation in maize roots. [PDF]
An endopeptidase (designated RSIP, for root-starvation-induced protease) was purified to homogeneity from glucose-starved maize roots. The molecular mass of the enzyme was 59 kDa by SDS/PAGE under reducing conditions and 62 kDa by gel filtration on a Sephacryl S-200 column. The isoelectric point of RSIP was 4.55. The purified enzyme was stable, with no

Analysis of a Lys-specific serine endopeptidase secreted via the type IX secretion system in Porphyromonas gingivalis. [PDF]
Porphyromonas gingivalis, a significant causative agent of adult periodontitis, possesses a novel secretion system called the type IX secretion system (T9SS). A number of virulence factors, such as Arg-gingipain (Rgp), are translocated onto the cell surface and into the extracellular milieu via the T9SS. In this study, we found that the PGN_1416 90- to

SmSP2: A serine protease secreted by the blood fluke pathogen Schistosoma mansoni with anti-hemostatic properties. [PDF]
BACKGROUND:Serine proteases are important virulence factors for many pathogens. Recently, we discovered a group of trypsin-like serine proteases with domain organization unique to flatworm parasites and containing a thrombospondin type 1 repeat (TSR-1 ...

Prolyl endopeptidase-like is a (thio)esterase involved in mitochondrial respiratory chain function
Summary: Deficiency of the serine hydrolase prolyl endopeptidase-like (PREPL) causes a recessive metabolic disorder characterized by neonatal hypotonia, feeding difficulties, and growth hormone deficiency.

Sensitive substrates for neprilysin (neutral endopeptidase) and thermolysin that are highly resistant to serine proteases [PDF]
Tripeptide derivatives like 3‐carboxypropanoylalanyl‐alanyl‐leucine 4‐nitroanilide or 3‐carboxypropanoylalanyl‐alanyl‐phenylalanine 4‐nitroanilide are very sensitive substrates for neprilysin (k cat > 102 s−1; k cat/K m ≥ 106 s−1 · M−1) and are widely employed in investigations of the enzyme. However, these compounds are also good substrates for the

Infection by Staphylococcus epidermidis, an opportunistic pathogen, has become a major problem due to the increased use of implanted medical devices and the growing number of patients who are therapeutically or infectiously immunosuppressed. These infections appear to proceed via modulation of the coagulation and complement systems.
