Tryptophan synthase of Neurospora crassa was purified to electrophoretic homogeneity from the wild type strain 74A which had been derepressed by the presence of 0.5 rnr,r indoleacrylic acid in the growth medium. The isolated material migrated as a single symmetrical peak in the ultracentrifuge with a sedimentation constant of 6.0 S. Gel filtration on Sephadex G-ZOO and conventional sedimentatio...
Tryptophan synthase of Neurospora crassa was purified to electrophoretic homogeneity from the wild type strain 74A which had been derepressed by the presence of 0.5 mM indoleacrylic acid in the growth medium. The isolated material migrated as a single symmetrical peak in the ultracentrifuge with a sedimentation constant of 6.0 S. Gel filtration on Sephadex G-200 AND CONVENTIONAL SEDIMENTATION E...
Thaxtomin phytotoxins produced by plant-pathogenic Streptomyces species contain a nitro group that is essential for phytotoxicity. The N,N'-dimethyldiketopiperazine core of thaxtomins is assembled from L-phenylalanine and L-4-nitrotryptophan by a nonribosomal peptide synthetase, and nitric oxide synthase-generated NO is incorporated into the nitro group, but the biosynthesis of the nonproteinog...
