In 1964, JE Falk was able to give one man's view of the porphyrinand metalloporphyrin field
at possibly the last time that such a major task was possible. Since then the area has …

A reaction path is presented by which the effects of oxygen binding in hemoglobin are
transmitted from a heme group to the surface of its subunit. Starting from the known deoxy …

Studies of high spin ferrous and ferric deriva-tives led us to conclude that in the quaternary R
