Biogenesis of chromomycin A3 by Streptomyces griseus.
The biosynthesis of chromomycin A3 was investigated using 13C-labeled acetates, methionine and glucose, and 13C,18O-labeled acetate. 13C NMR spectral analysis demonstrated that: Aglycone assembly occurs by combining at least two polyketide chains; three of nine oxygen atoms of the aglycone originate from acetate precursor oxygen atoms; carbon methylations on the aromatic ring at C-7, on the chr...
متن کاملCredibility of Chromomycin A3 Staining in Prediction of Fertility
Background Chromomycin A3 (CMA3) staining has been used to assess protamine deficiency. The aim of this study was to determine credibility of CMA3 along with semen parameters for assessment of fertility potential. MaterialsAndMethods Semen analysis and CMA3 staining were carried out on 234 fertile and 178 subfertile individuals. Semen analysis was assessed according to WHO criteria. Protamine d...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
