Catalytic properties of the cysteine aminopeptidase PepC, a bacterial bleomycin hydrolase
BBA - Proteins and Proteomics, 1998PepC is a cytoplasmic thiol aminopeptidase widely conserved among lactic acid bacteria. PepC from Lactococcus lactis shares 35-38% identity with aminopeptidases of eukaryotic origins: the yeast and mammalian bleomycin hydrolases (BLMase). In this work we investigated the hydrolytic activity of PepC towards various substrates: bleomycin A2, aminoacyl-p ...

Arabidopsis ppc3 mutant has a growth-arrest phenotype and is affected in phosphate- and salt-stress responses, showing that this protein is crucial under control or stress conditions. Phosphoenolpyruvate carboxylase (PEPC) and its dedicated kinase (PEPC-k) are ubiquitous plant proteins implicated in many physiological processes.

The aminopeptidase C (PepC) of Lactobacillus helveticus CNRZ32 was purified by anion exchange chromatography from cell free extracts of an E. coli DH5α clone overexpressing the Lactobacillus aminopeptidase. PepC was found to have a tetrameric structure in its native form with subunits of 50 kDa each, a pH optimum of 6.5 and maximum activity at 45 °C ...

Scalasca Parallel Performance Analyses of PEPC
2009PEPC (Pretty Efficient Parallel Coulomb-solver) is a complex HPC application developed at the Julich Supercomputing Centre, scaling to thousands of processors. This is a case study of challenges faced when applying the Scalasca parallel performance analysis toolset to this intricate example at relatively high processor counts. The Scalasca version used

Inhibition of the enzyme phosphoenolpyruvate-carboxylase (PEPC) by different pollutants
Talanta, 1997The inhibitory effect of different pollutants on the enzyme phosphoenolpyruvate-carboxylase was investigated. For this enzyme, different procedures are described for determining the activity of the enzyme. Determination of the presence of the enzymatically-formed oxaloacetate was found to be more suitable for this purpose because of the higher ...

PEPC [PEP (phosphoenolpyruvate) carboxylase] is a tightly controlled enzyme located at the core of plant C-metabolism that catalyses the irreversible β-carboxylation of PEP to form oxaloacetate and Pi. The critical role of PEPC in assimilating atmospheric CO2 during C4 and Crassulacean acid metabolism photosynthesis has been studied extensively.

V2O4–PEPC composite based pressure sensor
Microelectronic Engineering, 2011In this study, V"2O"4-PEPC based pressure sensor was designed and fabricated by drop-casting the blend of V"2O"4-PEPC microcomposite thin films of vanadium oxide (V"2O"4) micropowder (10wt.%) and poly-N-epoxypropylcarbazole, PEPC (2wt.%) in benzol (1ml) on steel substrates. The thickness of the V"2O"4-PEPC films was in the range of 20-40@mm.

Optical and electrophysical properties of Ag–PEPC nanocomposites
Materials Science and Engineering: C, 2006Absorption and luminescence spectra as well as the temperature dependences of electrical conductivity of polyepoxypropylcarbazole (PEPC) with Ag nanoparticles are studied. Polyepoxypropylcarbazole results in an additional stabilization of Ag nanoparticles. They cause essential PEPC photoluminescence quenching.
