Characterization of two glycosyltransferases involved in early glycosylation steps during biosynthesis of the antitumor polyketide mithramycin by Streptomyces argillaceus
A 2580-bp region of the chromosome of Streptomyces argillaceus, the producer of the antitumor polyketide mithramycin, was sequenced. Analysis of the nucleotide sequence revealed the presence of two genes (mtmGII...

Three Nrt2 genes are differentially regulated in Chlamydomonas reinhardtii
Two new nitrate assimilation-related genes, Nrt2;3 and Nar5, have been identified in Chlamydomonas reinhardtii. The Nrt2;3 gene is a new member of the Nrt2 family, encoding high-affinity nitrate (nitrite) transp...

An ABC transporter is essential for resistance to the antitumor agent mithramycin in the producerStreptomyces argillaceus
Mithramycin is an antitumor antibiotic synthesized byStreptomyces argillaceus. This producer strain is highly resistant in vivo to mithramycin (MIC 100 µg/ml) but sensitive to the related drugs chromomycin and ol...

Isolation and characterization of two new negative regulatory mutants for nitrate assimilation inChlamydomonas reinhardtii obtained by insertional mutagenesis
Plasmid DNA carrying either the nitrate reductase (NR) gene or the argininosuccinate lyase gene as selectable markers and the correspondingChlamydomonas reinhardtii mutants as recipient strains have been used to ...
