limited proteolysis of phosphorylated synapsin i by v8 protease , alpha-chymotrypsin or collagenase , performed on the isolated dimer and monomer , allows us to localize tentatively in the central hydrophobic core of the molecule the cysteine residues the oxidation of which by copper/o-phenanthroline gives rise to synapsin dimers .
