Bacillus pasteurii UreE (BpUreE) is a putative chap- erone assisting the insertion of Ni 2 ions in the active site of urease. The x-ray structure of the protein has been determined for two crystal forms, at 1.7 and 1.85 Å resolution,... more
Using affinity chromatography on 8-(2-aminoethyl)-amino-cAMP Sepharose, the cGMP-dependent protein kinase (ATP: protein phosphotransferase, EC 2.7.1.37) from tissues of the prawn Palaemon adspersus was purified to homogeneity as... more
Using ion-exchange chromatography and gel filtration, cGMP-dependent protein kinase was purified from prawn tissues 220-fold with a yield of activity of 12%. The apparent Ka values for cGMP, cAMP and 8-Br-cGMP are 1 . 10(-7), 5 . 10(-6)... more
Porphyrin nanotubes have been obtained from tetrakis (4-sulfonatophenil) porphyrin (TTPS4) using ionic self-assembly, and UV-vis spectra have been recorded. pH titration of the Soret band has been performed at 420 nm. It has been shown... more
The paper deals with the mechanism of the phosphotransferase reaction catalyzed by G-kinase purified from the shrimp tissue by affinity chromatography. The ATP functional groups are stated to be significant for interaction with the... more
Selective Escherichia coli β-glucuronidase (eGUS) inhibitors, which do not affect human β- glucuronidase (hGUS), greatly alleviate side effects (severe diarrhea) of worldwide used chemotherapeutics, camptothecin and its derivatives. We... more
UreE is a homodimeric metallo-chaperone that assists the insertion of Ni(2+) ions in the active site of urease. The crystal structures of UreE from Bacillus pasteurii and Klebsiella aerogenes have been determined, but the details of the... more
