The reactions of a phenazine dye, methylene blue with sulfydryl substrates have been investigated in acidic medium in presence of metal ions CuII and RuIII. The substrates are the functional parts of active biomolecules and our investigation reveals that the kinetics of these reactions are appreciably influenced by the environmental and the steric factors. The mechanistic conclusions partly explain the complexity of biochemical processes involving these substrates.
