A reagent for reduction of disulfide bonds in proteins that reduces disulfide bonds faster than does dithiothreitol
摘要:
We have synthesized a new reagent--N,N'-dimethyl-N,N'-bis(mercaptoacetyl)hydrazine (DMH)-for the reduction of disulfide bonds in proteins. DMH reduces disulfid bonds 7 times faster than does dithiothreitol (DTT) in water at pH 7. DMH reduces mixed disulfides of cysteine proteases (papain and ficin) especially rapdily (30 times faster than DTT). DMH (epsilon-degrees = -0.300 V) reduces noncyclic disulfides completely, although it is less strongly reducing than DTT (epsilon-degrees = -0.356 V).
