Sequencing was performed in a gas-phase protein sequencer by automated Edman degradation of the S-carboxymethylated toxin and fragments of it produced by reaction with CNBr. Versutoxin consisted of a single chain of 42 amino acid residues. It was found to have a high proportion of basic residues and of cystine. The primary structure showed marked homology with that of robustoxin, a novel neurotoxin recently isolated from the venom of another funnel-web-spider species, Atrax robustus.<\/jats:p>","DOI":"10.1042\/bj2500401","type":"journal-article","created":{"date-parts":[[2015,8,10]],"date-time":"2015-08-10T21:10:03Z","timestamp":1439241003000},"page":"401-405","update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":70,"title":["Amino acid sequence of versutoxin, a lethal neurotoxin from the venom of the funnel-web spider <i>Atrax versutus<\/i>"],"prefix":"10.1042","volume":"250","author":[{"given":"M R","family":"Brown","sequence":"first","affiliation":[{"name":"School of Chemistry, Macquarie University, Sydney, N.S.W. 2109, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D D","family":"Sheumack","sequence":"additional","affiliation":[{"name":"School of Chemistry, Macquarie University, Sydney, N.S.W. 2109, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M I","family":"Tyler","sequence":"additional","affiliation":[{"name":"School of Chemistry, Macquarie University, Sydney, N.S.W. 2109, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M E H","family":"Howden","sequence":"additional","affiliation":[{"name":"School of Chemistry, Macquarie University, Sydney, N.S.W. 2109, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"288","container-title":["Biochemical Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/portlandpress.com\/biochemj\/article-pdf\/250\/2\/401\/592375\/bj2500401.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/portlandpress.com\/biochemj\/article-pdf\/250\/2\/401\/592375\/bj2500401.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,11,25]],"date-time":"2021-11-25T17:58:13Z","timestamp":1637863093000},"score":1,"resource":{"primary":{"URL":"https:\/\/portlandpress.com\/biochemj\/article\/250\/2\/401\/23655\/Amino-acid-sequence-of-versutoxin-a-lethal"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1988,3,1]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[1988,3,1]]}},"URL":"https:\/\/doi.org\/10.1042\/bj2500401","relation":{},"ISSN":["0264-6021","1470-8728"],"issn-type":[{"value":"0264-6021","type":"print"},{"value":"1470-8728","type":"electronic"}],"subject":[],"published":{"date-parts":[[1988,3,1]]}}}
