Recently, a fair amount of work has been done on the effect of lead on porphobilinogen dehydratase, which has been used as a sensitive indicator of lead poisoning. How far this is in itself harmful depends on the Michaelis constants of both the aminolaevulinic synthetase and of the dehydratase, and in addition on the relative activities of the two enzymes in a cell and also on the tissue concentration of glycine. Information on some of these points is still fragmentary, and a reliable judgement is at the present not very easy. Another step in the heme synthesis, which is sensitive to low concentrations of lead, is the incorporation of iron into protoporphyrin. Inhibition of this step may be important in accounting to a large extent for the ...
