Genome Announc. 2015 Feb 19;3(1). | Draft Genome Sequence of Marine-Derived Streptomyces sp. TP-A0873, a Producer of a Pyrrolizidine Alkaloid Bohemamine.[Pubmed: 25700394] | METHODS AND RESULTS:
Streptomyces sp. TP-A0873, isolated from deep-sea water, produces three different classes of secondary metabolites: antimycin, Bohemamine, and alkylated butenolides. In order to assess the biosynthetic potential of this strain, draft genome sequencing was carried out.
CONCLUSIONS:
The genome contained at least 14 gene clusters for polyketide synthase (PKS) and nonribosomal peptide synthetase (NRPS). | J Antibiot (Tokyo). 2003 Aug;56(8):673-81. | New cell-cell adhesion inhibitors from Streptomyces sp. UMA-044.[Pubmed: 14563155] | METHODS AND RESULTS: Three compounds, NP25301 (1), NP25302 (2) and bohemamine (3), inhibitors of cell adhesion based on LFA-1/ICAM-1, were isolated from the cultured broth of the strain Streptomyces sp. UMA-044. New compounds 1 and 2 were identified as 2-(3'-carbamoylphenoxy)acrylic acid methyl ester and deoxybohemamine, respectively, based on spectroscopic analyses.
CONCLUSIONS:
Compounds 1 approximately 3 inhibited adhesion of HL-60 cells to CHO-ICAM-1 cells at IC50 values of 29.5 microg/ml for 1, 24.3 microg/ml for 2, and 27.2 microg/ml for 3. |
