Recently, we found that Streptomyces olivochromogenes NBRC 3561 produced a bioactive peptide, so we sequenced its genome to clarify its biosynthesis. We report here the draft genome sequence of S. olivochromogenes NBRC 3561, in which 40 potential secondary metabolite gene clusters were predicted by antiSMASH.

Metabolomics and genomics are two complementary platforms for analyzing an organism as they provide information on the phenotype and genotype, respectively. These two techniques were applied in the dereplication and identification of bioactive compounds from a Streptomyces sp. (SM8) isolated from the sponge Haliclona simulans from Irish waters. Streptomyces strain SM8 extracts showed antibacter...

We report here a sequence of the genome of the Streptomyces fradiae ATCC 19609 strain, initially isolated from the soil, which produces tylosin. S. fradiae is highly sensitive to different classes of antibiotics, compared to the sensitivities of other bacteria. We have identified 9 groups of genes directly or indirectly involved in the resistome formation.

Streptomyces vitaminophilus produces pyrrolomycins, which are halogenated polyketide antibiotics. Some of the pyrrolomycins contain a rare nitro group located on the pyrrole ring. The 6.5-Mbp genome encodes 5,941 predicted protein-coding sequences in 39 contigs with a 71.9% G+C content.

Strain DH-12 exhibits broad-spectrum antibacterial activity toward Gram-positive and Gram-negative pathogens. The 7.6-Mb draft genome sequence gives insight into the complete secondary metabolite production capacity and reveals genes putatively responsible for its antibacterial activity, as well as genes which enable the survival of the organism in an extreme arid environment.

Amela and Verse are two Streptomyces phages isolated by enrichment on Streptomyces venezuelae (ATCC 10712) from two different soil samples. Amela has a genome length of 49,452, with 75 genes. Verse has a genome length of 49,483, with 75 genes. Both belong to the BD3 subcluster of Actinobacteriophage.

Many pathogenic bacteria secrete $-lactamase enzymes as a mechanism of defence against $-lactam antibiotics. A new Streptomyces sp., NRC-77, was isolated from an Egyptian soil sample. The NRC-77 strain has biochemical, chemotaxonomic, morphological and physiological properties consistent with classification in the genus Streptomyces, with the nearest species being Streptomyces rochei. Furthermo...

Streptomyces sp. strain K30 induces the formation of an extracellular Lcp (latex-clearing protein) during poly(cis-1,4-isoprene) degradation. To investigate the function of this enzyme in Streptomyces sp. strain K30, the lcp gene was disrupted. This was the first time that the screening for a knock out lcp mutant of Streptomyces sp. strain K30 was successful. The resulting mutant Streptomyces s...
