The interaction of copper oxide nanoparticles and copper ions and proteinase K from Tritirachium album Limber has been investigated employing UV spectroscopy and kinetics measurements. The aim of this study was to evaluate the effect of nanoparticles of CuO for proteinase K. In this paper we compare the effect of copper oxide nanoparticles with the effect of copper ions on proteinase K sta...

The cbsA gene encoding the collagen-binding S-layer protein of Lactobacillus crispatus JCM5810 was expressed in L. casei ATCC 393(T). The S-protein was not retained on the surface of the recombinant bacteria but was secreted into the medium. By translational fusion of CbsA to the cell wall sorting signal of the proteinase, PrtP, of L. casei, CbsA was presented at the surface, rendering the tran...

A cytokine that inhibits fibrinolysis has been detected in the serum-free culture medium of guinea pig and hamster fibroblasts. This proteinase inhibitor was also present in Triton X-100 extracts of guinea pig cells. It was stable at pH 3.0 for 2 hr and was produced by cells rather than assimilated from serum in the culture medium as evidenced by: (a) an apparent molecular size (less than 45 ki...
