Biosynthetic studies on validamycins. I. 1H and 13C NMR assignments of validamycin A.
نویسندگان
چکیده
The 1H and 13C NMR spectra of validamycin A have been assigned by use of 2D homonuclear correlation spectroscopy for protons, and off-resonance decoupling, single frequency off-resonance decoupling, and comparison studies with model compounds for carbons. Effects of pH on carbon chemical shifts have also been studied.

Microbial transformation of validamycins.
Alpha- or beta-Glucosidic linkage of validamycin was selectively cleaved by microbial hydrolysis and especially the conversion of validamycin C into validamycin A by the selective hydrolysis of alpha-glucoside linkage has important significance because validamycin C is considerably less active than validamycin A. Semisyntheses of validamycins including a new validamycin, beta-D-galactosyl-vali...

Some of the Adamantane properties were calculated in this study. Chemical shift, free energy ofsolvation, free energy of cavity formation, Henry's law constant, and other properties ofAdamantane in dry phase, three solvents and three temperatures have been calculated with Abinitio method base on density functional theory (DFT) at B3lyp/6-31g, B31yp/6-31g*, B3lyp/6-31+g* and B3lyp/6-31++g** leve...
متن کاملNMR with 13C, 15N-doubly-labeled DNA: the Antennapedia homeodomain complex with a 14-mer DNA duplex.
Nearly complete 1H, 13C and 15N NMR assignments have been obtained for a doubly labeled 14-base pair DNA duplex in solution both in the free state and complexed with the uniformly 15N-labeled Antennapedia homeodomain. The DNA was either fully 13C, 15N-labeled or contained uniformly 13C, 15N-labeled nucleotides only at those positions which form the protein-DNA interface in the previously determ...

متن کاملBackbone assignments and secondary structure of the Escherichia coli enzyme-II mannitol A domain determined by heteronuclear three-dimensional NMR spectroscopy.
This report presents the backbone assignments and the secondary structure determination of the A domain of the Escherichia coli mannitol transport protein, enzyme-IImtl. The backbone resonances were partially assigned using three-dimensional heteronuclear 1H NOE 1H-15N single-quantum coherence (15N NOESY-HSQC) spectroscopy and three-dimensional heteronuclear 1H total correlation 1H-15N single-q...
