title: Methylphenylmercury: a novel heavy atom reagent for protein crystallography.
abstract: Methylphenylmercury reacts with two normally inaccessible cysteine residues in crystals of carbonmonoxyhaemoglobin, but not with the third, normally reactive one. It may, therefore, be useful in the preparation of new heavy atom derivatives for protein crystallography.
