Incubation of pig kidney microvillar membranes with Bacillus thuringiensis or Staphylococcus aureus phosphatidylinositol-specific phospholipase C (PI-PLC) resulted in the release of a number of glycosyl-phosphatidylinositol (GPI)-anchored hydrolases, including alkaline phosphatase (EC 3.1.3.1), amino-peptidase P (EC 3.4.11.9), membrane dipeptidase (EC 3.4.13.19), 5'-nucleotidase (EC 3.1.3.5) an...
Renal dipeptidase (EC 3.4.13.11) was solubilized from pig kidney microvillar membranes with bacterial phosphatidylinositol-specific phospholipase C and then purified by affinity chromatography on cilastatinSepharose. The enzyme was apparently homogeneous on SDS/polyacrylamide-gel electrophoresis with an Mr of 47000. Immunohistochemical analysis of the distribution of the dipeptidase showed it t...
Extracts prepared from tissue with granulomatous inflammation experimentally produced in liver of CBA-strain mice showed increased hydrolysis of leukotriene D4 (LTD4), Leu-Leu and Ala-Gly as compared with normal hepatic cells. Two dipeptidases, Leu-Leu dipeptidase and Ala-Gly dipeptidase, were purified from hepatic granulomas, and quantitative conversion of LTD4 into leukotriene E4 (LTE4) by bo...
Clones expressing renal dipeptidase (EC 3.4.13.11) have been isolated from a pig kidney cortex cDNA library after employing the polymerase chain reaction technique to amplify a region of the dipeptidase cDNA. The complete primary sequence of the enzyme has been deduced from a full length cDNA clone. This predicts a protein of 409 amino acids, a cleavable N-terminal signal sequence of 16 residue...
Membrane dipeptidase (EC 3.4.13.19) enzyme activity that is inhibited by cilastatin has been detected in pancreatic zymogen granule membranes of human, porcine and rat origin. Immunoelectrophoretic blot analysis of human and porcine pancreatic zymogen granule membranes with polyclonal antisera raised against the corresponding kidney membrane dipeptidase revealed that the enzyme is a disulphide-...
1. Rats were mated and at weekly intervals during pregnancy and lactation, and after weaning, the dipeptidase activity in the supernatant fraction from small intestinal mucosa extracts was determined for two dipeptides: glycyl-L-leucine dipeptidase (EC 3.4.3.2) AND L-alanyl-L-glutamic acid dipeptidase. 2. Dipeptidase activity is found mainly in the soluble (spernantant) fraction of the mucosa h...
A dipeptidase was purified from a cell extract of Bifidobacterium longum BORI by ammonium sulfate precipitation and chromatography on DEAE-cellulose and Q-Sepharose columns. The purified dipeptidase had a molecular mass of about 49 kDa and was optimally active at pH 8.0 and 50 degrees C. The enzyme was a strict dipeptidase, being capable of hydrolyzing a range of dipeptides but not tri- and tet...
No. Haka7191 Beamline(s): X4A, X12C Introduction: Aspartyl dipeptidase (peptidase E) and tripeptidase (peptidase T) from Salmonella typhimurium are intracellular peptidases with very different specificities and structures. Aspartyl dipeptidase is a serine hydrolase that cleaves dipeptides with an N-terminal aspartate, and tripeptidase is a metallopeptidase that releases the N-terminal, preferab...
The gene pepV, encoding a dipeptidase from Lactococcus lactis subsp. cremoris MG1363, was identified in a genomic library in pUC19 in a peptidase-deficient Escherichia coli strain and subsequently sequenced. PepV of L. lactis is enzymatically active in E. coli and hydrolyzes a broad range of dipeptides but no tri-, tetra-, or larger oligopeptides. Northern (RNA) and primer extension analyses in...
Renal dipeptidase (EC 3.4.13.11) has been purified from human kidney cortex by affinity chromatography on cilastatin-Sepharose following solubilization with either n-octyl-beta-D-glucopyranoside or bacterial phosphatidylinositol-specific phospholipase C (PI-PLC). Phase separation in Triton X-114 revealed that the detergent-solubilized form was amphipathic and retained the glycosyl-phosphatidyli...
