Here we report that S1P is also involved in the processing of the GPs of the genetically more-distant South American hemorrhagic fever viruses Guanarito, Machupo, and Junin. Efficient cleavage of Guanarito virus GP, whose protease recognition sites deviate from the reported S1P consensus sequence, indicates a broader specificity of S1P than anticipated. Lack of GP processing of Junin virus dramatically reduced production of infectious virus and prevented cell-to-cell propagation. Infection of S1P-deficient cells resulted in viral persistence over several weeks without the emergence of escape variants able to use other cellular proteases for GP processing.\n          <\/jats:p>","DOI":"10.1128\/jvi.02392-07","type":"journal-article","created":{"date-parts":[[2008,4,10]],"date-time":"2008-04-10T00:54:00Z","timestamp":1207788840000},"page":"6045-6051","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":88,"title":["Site 1 Protease Is Required for Proteolytic Processing of the Glycoproteins of the South American Hemorrhagic Fever Viruses Junin, Machupo, and Guanarito"],"prefix":"10.1128","volume":"82","author":[{"given":"Jillian M.","family":"Rojek","sequence":"first","affiliation":[{"name":"Molecular and Integrative Neurosciences Department (MIND), The Scripps Research Institute, La Jolla, California 92037"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew M.","family":"Lee","sequence":"additional","affiliation":[{"name":"Molecular and Integrative Neurosciences Department (MIND), The Scripps Research Institute, La Jolla, California 92037"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"NgocThao","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Molecular and Integrative Neurosciences Department (MIND), The Scripps Research Institute, La Jolla, California 92037"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christina F.","family":"Spiropoulou","sequence":"additional","affiliation":[{"name":"Special Pathogens Branch, Centers for Disease Control and Prevention, Atlanta, Georgia 30333"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefan","family":"Kunz","sequence":"additional","affiliation":[{"name":"Molecular and Integrative Neurosciences Department (MIND), The Scripps Research Institute, La Jolla, California 92037"},{"name":"Institute of Microbiology, University Hospital Center and University of Lausanne, Lausanne, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.77.5.2866-2872.2003"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0092-8674(00)80213-5"},{"key":"e_1_3_2_4_2","first-page":"1791","year":"2007","unstructured":"Buchmeier, M.
