The complex was then passed through a 0.45 μM cellulose acetate spin filter and set up for crystallization using an NT-8 crystallization robot (Formulatrix). Using MRC-2 crystallization plates, wells containing 40 μL of 10% w/v PEG 6000, 0.1 M MES pH 6.0, and 10% glycerol were dispensed, and then sitting drops consisting of 0.15 μL protein were set up against a 0.15 μL well buffer. Crystallization plates were incubated at 21 °C, and rectangular crystals measuring 0.2 × 0.25 × 0.15 mm3 grew overnight. Crystals were flash-frozen in liquid nitrogen after being passed through a cryo consisting of a well buffer containing 20% glycerol.","divisions":[{"label":"title","span":{"begin":0,"end":22}}],"tracks":[{"project":"LitCovid-PD-FMA-UBERON","denotations":[{"id":"T42","span":{"begin":281,"end":290},"obj":"Body_part"},{"id":"T43","span":{"begin":569,"end":576},"obj":"Body_part"}],"attributes":[{"id":"A42","pred":"fma_id","subj":"T42","obj":"http://purl.org/sig/ont/fma/fma82748"},{"id":"A43","pred":"fma_id","subj":"T43","obj":"http://purl.org/sig/ont/fma/fma67257"},{"subj":"T42","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T43","pred":"source","obj":"LitCovid-PD-FMA-UBERON"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T193","span":{"begin":68,"end":71},"obj":"http://purl.obolibrary.org/obo/CL_0000784"},{"id":"T194","span":{"begin":133,"end":136},"obj":"http://purl.obolibrary.org/obo/CL_0000784"},{"id":"T195","span":{"begin":180,"end":183},"obj":"http://purl.obolibrary.org/obo/CLO_0001577"},{"id":"T196","span":{"begin":221,"end":223},"obj":"http://purl.obolibrary.org/obo/CLO_0050510"},{"id":"T197","span":{"begin":229,"end":233},"obj":"http://purl.obolibrary.org/obo/CLO_0001387"},{"id":"T198","span":{"begin":271,"end":272},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T199","span":{"begin":459,"end":462},"obj":"http://purl.obolibrary.org/obo/CLO_0050644"},{"id":"T200","span":{"begin":597,"end":598},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T201","span":{"begin":814,"end":815},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T202","span":{"begin":835,"end":836},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"}],"attributes":[{"subj":"T193","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T194","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T195","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T196","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T197","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T198","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T199","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T200","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T201","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T202","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-PD-CHEBI","denotations":[{"id":"T15929","span":{"begin":11,"end":13},"obj":"Chemical"},{"id":"T80857","span":{"begin":35,"end":37},"obj":"Chemical"},{"id":"T63926","span":{"begin":205,"end":207},"obj":"Chemical"},{"id":"T62765","span":{"begin":281,"end":298},"obj":"Chemical"},{"id":"T26566","span":{"begin":291,"end":298},"obj":"Chemical"},{"id":"T67725","span":{"begin":463,"end":466},"obj":"Chemical"},{"id":"T1016","span":{"begin":479,"end":482},"obj":"Chemical"},{"id":"T39607","span":{"begin":499,"end":507},"obj":"Chemical"},{"id":"T30005","span":{"begin":569,"end":576},"obj":"Chemical"},{"id":"T15551","span":{"begin":612,"end":618},"obj":"Chemical"},{"id":"T1021","span":{"begin":778,"end":786},"obj":"Chemical"},{"id":"T68914","span":{"begin":842,"end":848},"obj":"Chemical"},{"id":"T72200","span":{"begin":864,"end":872},"obj":"Chemical"}],"attributes":[{"id":"A46783","pred":"chebi_id","subj":"T15929","obj":"http://purl.obolibrary.org/obo/CHEBI_74795"},{"id":"A43267","pred":"chebi_id","subj":"T15929","obj":"http://purl.obolibrary.org/obo/CHEBI_90284"},{"id":"A53584","pred":"chebi_id","subj":"T80857","obj":"http://purl.obolibrary.org/obo/CHEBI_74795"},{"id":"A20702","pred":"chebi_id","subj":"T80857","obj":"http://purl.obolibrary.org/obo/CHEBI_90284"},{"id":"A77995","pred":"chebi_id","subj":"T63926","obj":"http://purl.obolibrary.org/obo/CHEBI_74795"},{"id":"A59876","pred":"chebi_id","subj":"T63926","obj":"http://purl.obolibrary.org/obo/CHEBI_90284"},{"id":"A16126","pred":"chebi_id","subj":"T62765","obj":"http://purl.obolibrary.org/obo/CHEBI_145232"},{"id":"A51127","pred":"chebi_id","subj":"T26566","obj":"http://purl.obolibrary.org/obo/CHEBI_30089"},{"id":"A88934","pred":"chebi_id","subj":"T26566","obj":"http://purl.obolibrary.org/obo/CHEBI_47622"},{"id":"A19284","pred":"chebi_id","subj":"T67725","obj":"http://purl.obolibrary.org/obo/CHEBI_46793"},{"id":"A67502","pred":"chebi_id","subj":"T1016","obj":"http://purl.obolibrary.org/obo/CHEBI_39005"},{"id":"A58008","pred":"chebi_id","subj":"T1016","obj":"http://purl.obolibrary.org/obo/CHEBI_39010"},{"id":"A92824","pred":"chebi_id","subj":"T39607","obj":"http://purl.obolibrary.org/obo/CHEBI_17754"},{"id":"A65959","pred":"chebi_id","subj":"T30005","obj":"http://purl.obolibrary.org/obo/CHEBI_36080"},{"id":"A21835","pred":"chebi_id","subj":"T15551","obj":"http://purl.obolibrary.org/obo/CHEBI_35225"},{"id":"A57823","pred":"chebi_id","subj":"T1021","obj":"http://purl.obolibrary.org/obo/CHEBI_25555"},{"id":"A54789","pred":"chebi_id","subj":"T68914","obj":"http://purl.obolibrary.org/obo/CHEBI_35225"},{"id":"A5818","pred":"chebi_id","subj":"T72200","obj":"http://purl.obolibrary.org/obo/CHEBI_17754"},{"subj":"T15929","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T80857","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T63926","pred":"sourc
