Glcnac biosynthesis and function, o linkedn
乙酰氨基葡萄糖的生物合成和功能 -
Hyaluronic acid ( ha ) is a high molecular weight linear polysaccharide composed of repeating disaccharide units of d - glucuronic acid ( glclia ) and n - acetyl - d - glucosamine ( glcnac ) linked by 3 - 1 - 3 and p - 1 - 4 glycoside bonds
透明質酸（ hyaluronicacid ）是一種由葡萄糖醛酸（ glcua ）和n -乙酰氨基葡萄糖（ clcnac ）以- 1 - 3和- 1 - 4糖苷鍵相連的二糖單位重復構建而成的，具有生物相容性的高分子聚合物。 -
And ha molecules were synthesized in vitro utilizing excessive active udp - glca and udp - glcnac sugar nucleotide precursors in the presence of a divalent mg2 + or mn2 + ion
經轉化大腸桿菌dh5a和iptg誘導表達，提取原生質膜在體外利用活性前驅物合成了透明質酸。以s -
Moreover, they have hi common the localization in the golgi apparatus, the topology of type ii membrane proteins, and the transfer of galactose from udp - galactose onto the c4 - hydroxyl group of glcnac residues
用iptg誘導表達的獲得- 1 ， 4 - gt與gst （谷胱甘肽轉移酶）的融合蛋白，經westernblot驗證與預想的一致。 -
Chitin synthase is the important enzyme that converts udp - glcnac to chitin
摘要幾丁質合成酶是生物合成幾丁質的關鍵物質。 -
These results indicate that the alteration of cell proliferation and dna synthesis caused by different gnt - v cdna transfection may at least partly result from the modification of n - glycan structure and function of egfr. it seems that the increased 1, 6 glcnac branch on the n - glycans of egfr may benefit to its binding with egf and the resulting tyrosine auto - phosphorylatio n, while the decrease of this branch may prevent these processes
用特異性抗體結合westemblot結果發現，正義或反義gnt一vcdna的轉染並不引起pkb 、 p44 / 42mapk和mek蛋白質表達的變化，而gntv一s / h 」 21細胞pkbt308 、 5473位點磷酸化和免疫沉澱pkb的酪氨酸磷酸化以及以gsk召a /日磷酸化為指標的pkb的活性都較mock細胞增加， gntv一as / h7721細胞中這些指標的變化則相反。 -
Therefore, the structural modification of n - glycan and the functional changes of egf receptor ( egfr ) in different transfected cells were investigated. it was found that the 1, 6 glcnac branch on the n - glycans of immuno - precipitated egfr on gntv - s / h7721 cells was increased while it was reduced in gntv - as / h7721 cell despite the unaltered expression of egfr protein
因此本文對不同轉染細胞egf受體（ egfr ）的糖鏈結構及功能的改變作進一步研究，結果發現，不同轉染細胞中，免疫沉澱egfr的蛋白量沒有改變，但gntv - s h7721細胞egfr上n -糖鏈中1 ， 6glcnac分支比mock細胞增多，而gntv - as h7721細胞相反。
