Specificity comparison of a serine endopeptidase (SH1) and a serine thiol endopeptidase (STH2) purified from human urine

The International Journal of Biochemistry & Cell Biology, 2004
In this study, we compared the properties of a serine endopeptidase H1 (SH1) and a serine thiol endopeptidase (STH2) purified from human urine by DEAE-cellulose followed by a Bio Gel A0.5 m or Sepharose Mercurial chromatographs. These enzymes differ in their action upon different hormone peptides.

Polyproline fold—In imparting kinetic stability to an alkaline serine endopeptidase

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2013
Polyproline II (PPII) fold, an unusual structural element was detected in the serine protease from Nocardiopsis sp. NCIM 5124 (NprotI) based on far UV circular dichroism spectrum, structural transitions of the enzyme in presence of GdnHCl and a distinct isodichroic point in chemical and thermal denaturation.

A serine endopeptidase from the fruits of Melothria japonica (Thunb.) Maxim.

Phytochemistry, 2001
An endopeptidase from the fruits of Melothria japonica (Thunb.) Maxim. has been purified by DEAE-Sepharose chromatography and gel-filtration by a Sephacryl S-300. The enzyme has Mr of 61 kDa. The optimum pH of the enzyme was 8. The enzyme activity was inhibited by diisopropyl fluorophosphate and phenylmethanesulfonylfluoride, but not by EDTA.

Comparative characterization of two serine endopeptidases from Nocardiopsis sp. NCIM 5124

Biochimica et Biophysica Acta (BBA) - General Subjects, 2000
A protease-producing, crude oil degrading marine isolate was identified as Nocardiopsis sp. on the basis of the morphology, cell wall composition, mycolic acid analysis and DNA base composition. The Nocardiopsis produces two extracellular proteases, both of which are alkaline serine endopeptidases.

Improved isolation, stability and substrate specificity of cucumisin, a plant serine endopeptidase

Biotechnology and Applied Biochemistry, 1995
Cucumisin (EC 3.4.21.25), a serine endopeptidase, was isolated by a simple purification procedure from the prince melon (Cucumis melo ssp. melo, cv. ‘Prince Melon’). The enzyme is stable over a wide pH range (4‐11) and to heat, 80% of its initial activity remaining even at pH 11.1 and at 60 degrees C for 20 min.

Heterozygous variants c.781G>A and c.1066dup ofserine protease 56cause familial nanophthalmos by impairing serine-type endopeptidase activity

British Journal of Ophthalmology, 2022
Background/aimsNanophthalmos is a rare developmental, bilateral, sporadic or hereditary form of microphthalmos. In this study, the heterozygous variants c.781G>A and c.1066dup of thePRSS56gene were identified in two patients with nanophthalmos. This study reports the clinical manifestation and the underlying pathogenic mechanism.MethodsWhole-exome ...

Yeast KEX2 gene encodes an endopeptidase homologous to subtilisin-like serine proteases

Biochemical and Biophysical Research Communications, 1988
Yeast Saccharomyces cerevisiae KEX2 gene previously isolated, was characterized as the gene encoding a calcium-dependent endopeptidase required for processing of precursors of alpha-factor and killer toxin. In this study, we report the amino acid sequence of the KEX2 gene product deduced from nucleotide sequencing.
