Ascaris suum
The nucleotide sequences of the mitochondrial DNA (mtDNA) molecules of two nematodes, Caenorhabditis elegans [13,794 nucleotide pairs (ntp)], and Ascaris suum (14,284 ntp) are presented and compared. Each molecule contains the genes for two ribosomal RNAs (+rRNA and 1-rRNA), 22 transfer RNAs (tRNAs) and 12 proteins, all of which are transcribed in the same direction. The protein genes are the s...
متن کاملDemonstration of cobamide coenzyme in Ascaris suum.
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 a...
متن کاملIntestinal Basement Membrane of Ascaris suum
The Ascaris suum intestinal basement membrane was solubilized on reduction with P-mercaptoethanol in 1% sodium dodecyl sulfate and 1% sodium dodecyl sulfate, 8 M urea to the extent of 90% and lOO%, respectively. The reduced membrane consists of at least 17 polypeptides ranging in molecular weight from 22,500 to greater than 400,000, as determined by sodium dodecyl sulfate-polyacrylamide gel ele...
متن کاملAscaris suum, an intestinal parasite, produces morphine.
The parasitic worm Ascaris suum contains the opiate alkaloid morphine as determined by HPLC coupled to electrochemical detection and by gas chromatography/mass spectrometry. The level of this material is 1168 +/- 278 ng/g worm wet weight. Furthermore, Ascaris maintained for 5 days contained a significant amount of morphine, as did their medium, demonstrating their ability to synthesize the opia...
متن کاملSubcellular localization of glyoxylate cycle enzymes in Ascaris suum larvae
Evidence is presented on the particulate nature of glyoxylate cycle enzymes in metazoa with the use of 15-day old larvae of the nematode Ascaris suum. Homogenization procedures were developed to disrupt the resistant nematode cuticle. Malate synthase and isocitrate lyase, key enzymes of the glyoxylate cycle, consistently sedimented with mitochondrial enzymes in differential pellets while catala...
