[5,8-13C2]Spermidine was prepared by synthesis, and its binding to macromolecular structures of Escherichia coli was studied. When added to E. coli cells, the two signals of [13C]spermidine (C-5, 47.8 ppm, and C-8, 39.6 ppm; JC-C = 5.8 Hz) were stron

Many hypotheses on uroporphyrinogen biosynthesis advanced the possibility that 2-aminomethyltripyrranes formed by porphobilinogen deaminase are further substrates or uroporphyrinogen III co-synthase in the presence of porphobilinogen. These proposals

The inhibitory effect of a series of 2-alkylputrescines on rat liver and Escherichia coli ornithine decarboxylase ( l -ornithine carboxy-lyase, EC 4.1.1.17) was examined. At 2.5 mM concentrations, 2-methyl-, 2-propyl-, 2-butyl-, 2-pentyl- and 2-hexyl

Porphobilinogen oxygenase oxidizes porphobilinogen to 2-hydroxy-5-oxo-porphobilinogen. This enzyme isolated from wheat germ has been purified to homogeneity, as judged by polyacrylamide gel electrophoresis under both nondenaturing and denaturing cond

The enzymatic oxidations of [alpha-14C]deuterohemin IX, [alpha-14C]hematohemin IX and 2,4-diacetyl[alpha-14C]deuterohemin IX were carried out by using a microsomal heme oxygenase system from rat liver in combination with the biliverdin reductase from

The substrate specificity of the different molecular forms of biliverdin reductase (bilirubin:NAD(P)+ oxidoreductase, EC 1.3.1.24) using biliverdin XIII alpha, XIII beta and XIII gamma was examined. It was found that molecular form 1 (the major form
