The K95 polysaccharide, which contains furanosidic 3-deoxy-D-manno-2-octulosonic acid (KDOf) residues, consists of----3)-beta-D-Rib-(1----8)-KDOf-(2----repeating units, has a molecular weight of approximately 25,000 (approximately 65 repeating units), and is randomly O-acetylated (1 acetyl group per repeating unit at unknown positions).","tracks":[{"project":"sentences","denotations":[{"id":"TextSentencer_T1","span":{"begin":0,"end":125},"obj":"Sentence"},{"id":"TextSentencer_T2","span":{"begin":126,"end":361},"obj":"Sentence"},{"id":"TextSentencer_T3","span":{"begin":362,"end":700},"obj":"Sentence"},{"id":"T1","span":{"begin":0,"end":125},"obj":"Sentence"},{"id":"T2","span":{"begin":126,"end":361},"obj":"Sentence"},{"id":"T3","span":{"begin":362,"end":700},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"TextSentencer_T1","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T2","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T3","pred":"source","obj":"sentences"},{"subj":"T1","pred":"source","obj":"sentences"},{"subj":"T2","pred":"source","obj":"sentences"},{"subj":"T3","pred":"source","obj":"sentences"}]},{"project":"NCBITAXON","denotations":[{"id":"T1","span":{"begin":34,"end":50},"obj":"OrganismTaxon"},{"id":"T2","span":{"begin":202,"end":218},"obj":"OrganismTaxon"}],"attributes":[{"id":"A1","pred":"db_id","subj":"T1","obj":"562"},{"id":"A2","pred":"db_id","subj":"T2","obj":"562"},{"subj":"T1","pred":"source","obj":"NCBITAXON"},{"subj":"T2","pred":"source","obj":"NCBITAXON"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"sentences","color":"#d193ec","default":true},{"id":"NCBITAXON","color":"#93ecb7"}]}]}}
