In addition to human patients, a Nubian goat with this disorder has been described and the caprine Glc6S (cGlc6S) cDNA cloned. In this study, the full-length cGlc6S cDNA was inserted into the expression vector, pEFNeo, which placed the cGlc6S cDNA under the transcriptional control of the human polypeptide chain elongation factor promoter. The pEFNeo expression vector also contains the human growth hormone polyadenylation signal and the genes encoding resistance to ampicillin and G418. The cGlc6S expression construct was electroporated into Chinese hamster ovary (CHO-K1) cells, and stably transfected clones were isolated. One clone, CHOrcGlc6S.17, which secreted the highest Glc6S activity into the culture medium, was selected and cultured in cell factories. The secreted recombinant cGlc6S (rcGlc6S) precursor was purified to homogeneity from conditioned medium by a two-column procedure which consisted of a Cu2+-chelating Sepharose column followed by TSK G3000SW gel filtration. The native molecular mass of rcGlc6S was estimated to be 102\u00a0kDa and the subunit size was 94\u00a0kDa. The kinetic properties of cGlc6S were similar to those of human Glc6S isolated from liver. rcGlc6S was endocytosed by fibroblasts from patients with mucopolysaccharidosis type IIID via the mannose 6-phosphate receptor-mediated pathway resulting in correction of the storage phenotype of these cells.<\/jats:p>","DOI":"10.1042\/bj3270089","type":"journal-article","created":{"date-parts":[[2015,8,10]],"date-time":"2015-08-10T21:56:29Z","timestamp":1439243789000},"page":"89-94","update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Expression, purification and characterization of recombinant caprine <i>N<\/i>-acetylglucosamine-6-sulphatase"],"prefix":"10.1042","volume":"327","author":[{"given":"Tom","family":"LITJENS","sequence":"first","affiliation":[{"name":"Lysosomal Diseases Research Unit, Department of Chemical Pathology, Women's and Children's Hospital, 72 King William Road, North Adelaide, South Australia 5006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julie","family":"BIELICKI","sequence":"additional","affiliation":[{"name":"Lysosomal Diseases Research Unit, Department of Chemical Pathology, Women's and Children's Hospital, 72 King William Road, North Adelaide, South Australia 5006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donald S.","family":"ANSON","sequence":"additional","affiliation":[{"name":"Lysosomal Diseases Research Unit, Department of Chemical Pathology, Women's and Children's Hospital, 72 King William Road, North Adelaide, South Australia 5006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karen","family":"FRIDERICI","sequence":"additional","affiliation":[{"name":"Department of Pathology, Michigan State University, 618 East Fee Hall, East Lansing, MI 48824-1314, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margaret Z.","family":"JONES","sequence":"additional","affiliation":[{"name":"Department of Pathology, Michigan State University, 618 East Fee Hall, East Lansing, MI 48824-1314, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John J.","family":"HOPWOOD","sequence":"additional","affiliation":[{"name":"Lysosomal Diseases Research Unit, Department of Chemical Pathology, Women's and Children's Hospital, 72 King William Road, North Adelaide, South Australia 5006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"288","container-title":["Biochemical Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/portlandpress.com\/biochemj\/article-pdf\/327\/1\/89\/624456\/bj3270089.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/portlandpress.com\/biochemj\/article-pdf\/327\/1\/89\/624456\/bj3270089.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,11,24]],"date-time":"2021-11-24T00:22:58Z","timestamp":1637713378000},"score":1,"resource":{"primary":{"URL":"https:\/\/portlandpress.com\/biochemj\/article\/327\/1\/89\/33262\/Expression-purification-and-characterization-of"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1997,10,1]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1997,10,1]]}},"URL":"https:\/\/doi.org\/10.1042\/bj3270089","relation":{},"ISSN":["0264-6021","1470-8728"],"issn-type":[{"value":"0264-6021","type":"print"},{"value":"1470-8728","type":"electronic"}],"subject":[],"published":{"date-parts":[[1997,10,1]]}}}
