Light-driven proton transport of bacteriorhodopsin incorporated into long-term stable liposomes of a polymerizable sulfolipid

1983

Abstract The chromoprotein bacteriorhodopsin from Halobacterium halobium has been incorporated into liposomes made of a fully synthetic, polymerizable lipid. Bacteriorhodopsin is found to be active in these polymer liposomes. The advantage in the use of such polymer systems concerning long-term stability in comparison with liposomes made of natural lipid is demonstrated.

Synaptobrevin cleavage by the tetanus toxin light chain is linked to the inhibition of exocytosis in chromaffin cells

1994

AbstractExocytosis of secretory granules by adrenal chromaffin cells is blocked by the tetanus toxin light chain in a zinc specific manner. Here we show that cellular synaptobrevin is almost completely degraded by the tetanus toxin light chain within 15 min. We used highly purified adrenal secretory granules to show that synaptobrevin, which can be cleaved by the tetanus toxin light chain, is localized in the vesicular membrane. Proteolysis of synaptobrevin in cells and in secretory granules is reversibly inhibited by the zinc chelating agent dipicolinic acid. Moreover, cleavage of synaptobrevin present in secretory granules by the tetanus toxin light chain is blocked by the zinc peptidase …

Promoter and exon–intron structure of the protein kinase C gene from the marine sponge Geodia cydonium: evolutionary considerations and promoter acti…

1999

Abstract We report the gene structure of a key signaling molecule from a marine sponge, Geodia cydonium. The selected gene, which codes for a classical protein kinase C (cPKC), comprises 13 exons and 12 introns; the introns are, in contrast to those found in cPKC from higher Metazoa, small in size ranging from 93 nt to 359 nt. The complete gene has a length of 4229 nt and contains exons which encode the characteristic putative regulatory and catalytic domains of metazoan cPKCs. While in the regulatory domain only one intron is in phase 0, in the catalytic domain most introns are phase 0 introns, suggesting that the latter only rarely undergo module duplication. The 5′-flanking sequence of t…

Tarantula hemocyanins imaged by atomic force microscopy

2004

Individual 4 x 6-meric tarantula hemocyanins and dissociation products were imaged by AFM in the non-contact mode. Although the resolution was low, the hexamers and topological arrangement within the oligomers can be seen. However, the relative humidity seems to affect the height profiles.
