چکیده

I. Cobamide coenzyme was extracted from the body wall of adult female Ascaris suum maintained in Ellison's medium containing vitamin B11• 2. The identification of the coenzyme in purified fractions was based on (a) specific spectral changes following treatment of the preparation with light and cyanide, (b) coenzyme activity in the glutamate mutase reaction and (c) inactivation of the coenzyme activity by light. 3. A fivefold increase in coenzyme occurre d in worms maintained in Ellison's medium plus vitamin B11, compared to the endogenous value. The data indicate that vitamin B11 is converted by A. suum into the metabolically active coenzyme.

Nematode pyruvate dehydrogenase kinases: role of the C-terminus in binding to the dihydrolipoyl transacetylase core of the pyruvate dehydrogenase complex.

Pyruvate dehydrogenase kinases (PDKs) from the anaerobic parasitic nematode Ascaris suum and the free-living nematode Caenorhabditis elegans were functionally expressed with hexahistidine tags at their N-termini and purified to apparent homogeneity. Both recombinant PDKs (rPDKs) were dimers, were not autophosphorylated and exhibited similar specific activities with the A. suum pyruvate dehydrog...

Comparative analysis of microRNA profiles between adult Ascaris lumbricoides and Ascaris suum

BACKGROUND The parasitic nematodes Ascaris lumbricoides and A. suum are of great public health and economic significance, and the two taxa were proposed to represent a single species. miRNAs are known with functions of gene regulations at post-transcriptional level. RESULTS We herein compared the miRNA profiles of A. lumbricoides and A. suum female adults by Solexa deep sequencing combined wi...

Isolation of Coenzyme B,, from Liver*

The identity of the major cobamide in liver has not been satisfactorily established. Cyanocobalamin (vitamin B12, 5,6dimethylbenzimidazolylcobamide cyanide), which has been obtained in crystalline form with liver as a source material (1, 2), is certainly a very minor component of the cobalamins in liver. Analyses of liver concentrates, both by a paper chromatographicbioautographic method (3) an...
