[Simultaneous determination of four Alternaria toxins in apple juice concentrate by ultra performance liquid chromatography-electrospray ionization tandem mass spectrometry].
Se Pu 28(12) , 1128-31, (2010) An ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/ MS) method was developed for the determination of altenuene (ALT), alternariol (AOH), tentoxin and alternariol monomethyl ether (AME) in apple juice concentrate (AJC). The sample wa... |

Hybrid Rhodospirillum rubrum F(0)F(1) ATP synthases containing spinach chloroplast F(1) beta or alpha and beta subunits reveal the essential role of the alpha subunit in ATP synthesis and tentoxin sensitivity.
J. Biol. Chem. 275(2) , 906-12, (2000) Trace amounts ( approximately 5%) of the chloroplast alpha subunit were found to be absolutely required for effective restoration of catalytic function to LiCl-treated chromatophores of Rhodospirillum rubrum with the chloroplast beta subunit (Avital, S., and ... |

Predicting the conformational states of cyclic tetrapeptides.
Biopolymers 69(3) , 363-85, (2003) Biologically active cyclic tetrapeptides, usually found among fungi metabolites, exhibit phytotoxic or cytostatic activities that are likely to be governed by specific conformations adopted in solution. For conformational studies and drug design, there is a s... |

Interrelation between high and low affinity tentoxin binding sites in chloroplast F1-ATPase revealed by synthetic analogues.
J. Biol. Chem. 273(6) , 3343-50, (1998) Eight synthetic analogues of tentoxin (cyclo-(L-N-MeGlu1-L-Leu2-N-MeDeltaZPhe3-Gly4)) modified in residues 1, 2, and 3 were checked for their ability to inhibit and reactivate the ATPase activity of the activated soluble part of chloroplast ATP synthase. The ... |

Demonstration of thermal dissipation of absorbed quanta during energy-dependent quenching of chlorophyll fluorescence in photosynthetic membranes.
FEBS Lett. 440(1-2) , 59-63, (1998) When plant leaves or chloroplasts are exposed to illumination that exceeds their photosynthetic capacity, photoprotective mechanisms such as described by the energy-dependent (non-photochemical) quenching of chlorophyll fluorescence are involved. The protecti... |

Role of the ATP synthase alpha-subunit in conferring sensitivity to tentoxin.
Biochemistry 40(25) , 7542-8, (2001) Tentoxin, produced by phytopathogenic fungi, selectively affects the function of the ATP synthase enzymes of certain sensitive plant species. Binding of tentoxin to a high affinity (K(i) approximately 10 nM) site on the chloroplast F(1) (CF(1)) strongly inhib... |

An insight into the mechanism of inhibition and reactivation of the F(1)-ATPases by tentoxin.
Biochemistry 41(19) , 6008-18, (2002) The mechanism of inhibition and reactivation of chloroplast ATP-synthase by the fungal cyclotetrapeptide tentoxin was investigated by photolabeling experiments, binding studies, and kinetic analysis using synthetic analogues of tentoxin. The alpha-subunit of ... |

Complete inhibition of the tentoxin-resistant F1-ATPase from Escherichia coli by the phytopathogenic inhibitor tentoxin after substitution of critical residues in the alpha - and beta -subunit.
J. Biol. Chem. 277(52) , 51003-7, (2002) Substitution of critical residues in the alpha- and beta-subunit can turn the typically resistant ATP synthase from the bacterium Escherichia coli into an enzyme showing high sensitivity to the phytopathogenic inhibitor tentoxin, which usually affects only ce... |

Metabolism of N-methyl-amide by cytochrome P450s: formation and characterization of highly stable carbinol-amide intermediate.
FEBS J. 278(12) , 2167-78, (2011) We report unambiguous proof of the stability of a carbinol intermediate in the case of P450 metabolism of an N-methylated natural cyclo-peptide, namely tentoxin. Under mild acidic or neutral conditions, the lifetime of carbinol-amide is long enough to be full... |
