The arrangement of the N-terminal part of subunit 4 (subunit b) has been studied by the use of mutants containing cysteine residues in a loop connecting the two N-terminal postulated membrane-spanning segments. Labelling of the mutated subunit 4 by the fluorescent probe N-(7-(dimethylamino)-4-methyl-3-coumarinyl)maleimide revealed that the sulfhydryl groups(More)
The interaction between the hydrophilic C-terminal part of subunit 4 (subunit b) and OSCP, which are two components of the connecting stalk of the yeast ATP synthase, was shown after reconstitution of the two over-expressed proteins and by the two-hybrid method. The organization of a part of the F0 sector was studied by the use of mutants containing(More)
Cultures of spinal cord neurons and cocultures of rat embryo neurons and muscle cells have been studied in the presence of tetanus toxin (TT) at a concentration of 40 micrograms/ml of medium. TT strongly stimulated neurite outgrowth, notably branching from the cell bodies. In addition it induced a marked, overall increase in acetylcholine receptor (AChR),(More)
The mean electrophoretic mobility (EPM) of splenic cells was determined in 4 different host-tumour systems. In splenic cells harvested from mice bearing slow-growing tumours, a significant EPM decrease was observed (12%) and in increase in the proportion of cells with slow mobility. Moreover, after 1 h incubation in RPMI medium at 37 degrees C and 2(More)
