Clostridium saccharobutyricum extracts, heat treated at 65° have somewhat similar properties to iron-deficient extracts prepared from this organism: they cannot degrade pyruvate by the phosphoroclastic pathway or incorporate 14CO2 into pyruvate. However, they stimulate the clastic activity of normal extracts and restore the clastic activity of aged extracts. A mixture of heat-treated (65°) and iron-deficient extracts is inactive. The heat-treated (65°) extract has no stimulating effect on the 14CO2-pyruvate exchange reaction. A cofactor FCL, of the formylfolic acid type was isolated from at 65° treated extracts. It increases the rat off oxidation of pyruvate. N10-formyltetrahydrofolic acid replaces FCL whereas folic, N10-formylfolic and N5-formyltetrahydrofolic acids are inactive.

A human abnormal hemoglobin with the electrophoretic mobility of hemoglobin J has been isolated and studied. The amino acid substitution in this abnormal hemoglobin has been investigated. It has been found that an aspartic acid residue substitutes in this hemoglobin J the glycine residue present in position 16 of the β peptide chain. There are reasons to believe that the hemoglobin J studied is different from other hemoglobin J's. Accordingly, the hemoglobin studied has been specifically designated hemoglobin JBaltimore.

The addition of ATP or PPi retarded conspicuously the rate of specific binding of trinitrobenzenesulfonate to one mole of lysine residue in 2.1·105 g of myosin A. The rate of specific binding of trinitrobenzenesulfonate to myosin A was increased in 4M LiBr which melts almost completely the helical structure of myosin A. The rate was also remarkably influenced by the treatment of myosin A with 1.5 M LiBr which inactivated ATPase (ATP phosphohydrolase, EC 3.6.1.3) without changing significantly the helical content of the myosin A molecule as a whole. Furthermore, it was demonstrated that actomyosin reconstituted from myosin A treated with p-chloromercuribenzoate and β-mercaptoethanol does not show a clearing response on addition of high concentrations of ATP and its ATPase activity is not inhibited by the substrate or by EDTA. The p-chloromercuribenzotae added was completely removed from myosin A by the further addition of excess β-mercaptoethanol and the optical rotatory dispersion of myosin A was insignificantly altered by the treatment with p-chloromercuribenzoate and β-mercaptoethanol.
