Ca(II)-calmodulin regulation of fungal dimorphism in Ceratocystis ulmi.
We have shown that Ca(II) ions, ethylene glycol-bis(beta-aminoethyl ether)-N,N-tetraacetic acid, LaCl3, and six known calmodulin inhibitors shift the yeast-mycelium dimorphic potential of Ceratocystis ulmi. Our data are consistent with the conclusions that Ca(II)-calmodulin interaction is necessary for mycelial growth in C. ulmi and that the absence of this interaction leads to the yeast phase.
متن کاملInhibition of polyketide synthesis in Alternaria alternata by the fatty acid synthesis inhibitor cerulenin.
The fatty acid synthase inhibitor cerulenin (50 to 100 micrograms/ml) inhibited production of the polyketide mycotoxins alternariol (AOH) and alternariol monomethyl ether (AME) by the mold Alternaria alternata. The results suggested that AOH synthesis was inhibited by a direct mechanism by cerulenin, whereas production of AME was probably limited by a shortage of the precursor AOH.
متن کاملThe antibiotic cerulenin, a novel tool for biochemistry as an inhibitor of fatty acid synthesis.
One ofthe most versatile uses of antibiotics is as potent drugs for clinical application. In recent years, attention has also been paid to agricultural uses of antibiotics, such as for feed additives for protecting plants and livestock against infectious diseases and for accelerating their growth. They are also used as food additives to retain freshness for an extended period. The usefulness of...
متن کاملEngineering fungal de novo fatty acid synthesis for short chain fatty acid production
Fatty acids (FAs) are considered strategically important platform compounds that can be accessed by sustainable microbial approaches. Here we report the reprogramming of chain-length control of Saccharomyces cerevisiae fatty acid synthase (FAS). Aiming for short-chain FAs (SCFAs) producing baker's yeast, we perform a highly rational and minimally invasive protein engineering approach that leave...
متن کاملLipoxygenase inhibitors shift the yeast/mycelium dimorphism in Ceratocystis ulmi.
The yeast-mycelium dimorphism in Ceratocystis ulmi, the causative agent of Dutch elm disease, was switched by gossypol, nordihydroguaiaretic acid, and propylgallate. In each case the mycelial form was converted to the yeast form. These compounds are recognized lipoxygenase inhibitors. Inhibitors of cyclooxygenase and thromboxane synthetase did not cause mycelia to shift to the yeast form. We su...
