Enhanced production of ansamitocin P-3 by addition of isobutanol in fermentation of Actinosynnema pretiosum.

Bioresour. Technol. 102 , 1863-1868, (2011)

Supply of isobutanol to enhance the production of anti-tumor agent ansamitocin P-3 (AP-3) in medium containing agro-industrial residues was investigated with analysis of gene transcription, enzyme activity, and intermediate accumulation. Under the optimal add...

Amide N-glycosylation by Asm25, an N-glycosyltransferase of ansamitocins.

Chem. Biol. 15(8) , 863-74, (2008)

Ansamitocins are potent antitumor maytansinoids produced by Actinosynnema pretiosum. Their biosynthesis involves the initial assembly of a macrolactam polyketide, followed by a series of postpolyketide synthase (PKS) modifications. Three ansamitocin glycoside...

Determination of the cryptic stereochemistry of the first PKS chain-extension step in ansamitocin biosynthesis by Actinosynnema pretiosum.

ChemBioChem. 7(8) , 1221-5, (2006)

The biosynthesis of the antitumor antibiotic, ansamitocin, involves the assembly of a linear octaketide on the ansamitocin (asm) polyketide synthase (PKS), which is then cyclized to proansamitocin and further modified to the final product. In the first chain-...

Cyclization of synthetic seco-proansamitocins to ansamitocin macrolactams by Actinosynnema pretiosum as biocatalyst.

ChemBioChem. 11(18) , 2517-20, (2010)

Bioreduction of aryl azides during mutasynthesis of new ansamitocins.

Org. Lett. 15(17) , 4442-5, (2013)

Supplementing a culture of a mutant strain of Actinosynnema pretiosum that is unable to biosynthesize aminohydroxy benzoic acid (AHBA), with 3-azido-5-hydroxy-benzoic acid and 3-azido-5-amino-benzoic acid, unexpectedly yielded anilino ansamitocins instead of ...

Enhanced production of ansamitocin P-3 by addition of Mg2+ in fermentation of Actinosynnema pretiosum.

Bioresour. Technol. 102(21) , 10147-50, (2011)

The effect of divalent metal ions (i.e., Mn(2+), Mg(2+), Zn(2+), Cu(2+), and Co(2+)) on the production of anticancer ansamitocin P-3 (AP-3) by submerged cultures of Actinosynnema pretiosum in medium containing agro-industrial residues was investigated, and Mg...

Constitutive overexpression of asm2 and asm39 increases AP-3 production in the actinomycete Actinosynnema pretiosum.

J. Ind. Microbiol. Biotechnol. 36(11) , 1345-51, (2009)

Constitutive overexpression of regulators in the ansamitocin biosynthetic cluster of Actinosynnema pretiosum was investigated as a strategy to increase the production of ansamitocin-P3 (AP-3), a clinically promising chemotherapeutic agent. Putative transcript...

A novel amide N-glycoside of ansamitocins from Actinosynnema pretiosum.

J. Antibiot. 57(5) , 348-50, (2004)

Dual Carbamoylations on the Polyketide and Glycosyl Moiety by Asm21 Result in Extended Ansamitocin Biosynthesis

Chem. Biol. 18(12) , 1571-80, (2011)

Carbamoylation is one of the post-PKS modifications in ansamitocin biosynthesis. A novel ansamitocinoside with carbamoyl substitution at the C-4 hydroxyl group of the N-β-D-glucosyl moiety was identified from the ansamitocin producer, Actinosynnema pretiosum....

New amide N-glycosides of ansamitocins identified from Actinosynnema pretiosum.

Arch. Pharm. Res. 30(6) , 670-3, (2007)

By using preparative TLC as the critical isolation procedure, two compounds, including one new amide N-glycosides of ansamitocin (2), were isolated from Actinosynnema pretiosum. The compounds were elucidated as N-demethyl-N-beta-D-glucopyranosyl ansamitocin P...
