A protein capable of activating 6-aminolevulinic acid synthetase has been purified from rat liver mitochondria. By treatment of the mitochondrial inner membrane-matrix fraction with Lubrol a soluble and active preparation of 6-aminolevulinic acid synthetase has been obtained. Ammonium sulfate fractionation yielded a 33 to 40% saturated fraction containing catalytic 6-aminolewlinic acid syntheta...
The effect of 5 drugs on the transport of several substrates, including the chemotherapeutic agent nitrogen mustard; choline; two nonmetabolizable amino acids, a-aminoisobutyric acid and cycloleucine; the glucose analog, 3-0-methyl-Dglucose; and the heme precursor, 6-aminolevulinic acid; was undertaken in L5178Y murine lymphoblasts in vitro. Trans port of both hydrolyzed nitrogen mustard and ch...
Yeast cells almost completely deficient in all cytochromes were obtained by introducing two defective nuclear genes, cyd1 and cyc4, into the same haploid strain. The action of the two mutant genes is synergistic, since either gene acting singly results in only partial cytochrome deficiency. Normal synthesis of all cytochromes can be restored in the double mutant by adding delta-aminolevulinic a...
