| pubmed-article:15315451 | pubmed:abstractText | Using a new approach based on the NMR spectroscopic analysis of the entire, unpurified spider venom, we identified a family of unusual sulfated nucleoside derivatives from the venom of the hobo spider, Tegenaria agrestis. These compounds are ribonucleoside mono- and disulfates derived from guanosine and xanthosine, some of which are glycosylated, bearing one or two D-fucose units. The use of NMR spectroscopy to characterize the unfractionated venom was central to the discovery of this heretofore overlooked class of venom components. | lld:pubmed |
