一般說明

尿苷5′-二磷酸-N-乙酰氨基葡糖(UDP-GlcNAc)是核苷酸糖。 由葡萄糖通过己糖胺生物合成途径(HBP)合成。UDP-GlcNAc由核苷酸糖转运蛋白(NST)主动转运至高尔基体中。UDP-GlcNAc的水平受细胞内营养物质浓度的调节。

應用

尿苷5′-二磷酸-N-乙酰氨基葡萄糖(UDP-GlcNAc)钠盐用作:
  • 作为内质网反应混合物的成分,用于高尔基体转运测定
  • 作为参考标准品,用高效液相色谱(HPLC)定量肝组织中UDP-GlcNAc
  • 检测 O-GlcNAc转移酶(OGT)对肽底物的糖基化活性

生化/生理作用

供体底物可用于在合成N-聚糖中将GlcNAc转移至多萜醇前体。 UDP-GlcNAc还在O-GlcNAc信号转导中通过O-GlcNAc转移酶(OGT)作为与丝氨酸/苏氨酸残基连接的GlcNAc的来源。
尿苷5′-二磷酸-N-乙酰氨基葡萄糖(UDP-GlcNAc)是糖供体,有助于内质网和高尔基体的膜内糖基化。 UDP-GlcNAc水平降低会影响细胞正常增殖和凋亡。UDP-GlcNAc引起谷氨酰胺果糖-6-磷酸酰胺基转移酶(GFAT)的反馈抑制。

Nuclear pore complexes (NPCs) control the traffic between cell nucleus and cytoplasm. While facilitating translocation of nuclear transport receptors (NTRs) and NTR·cargo complexes, they suppress passive passage of macromolecules 30 kDa. Previously, we reconstituted the NPC barrier as hydrogels comprising S.

Several pathogenic bacteria import and catabolize sialic acids as a source of carbon and nitrogen. Within the sialic acid catabolic pathway, the enzyme N-acetylmannosamine kinase (NanK) catalyzes the phosphorylation of N-acetylmannosamine to N-acetylmannosamine-6-phosphate. This kinase belongs to the ROK superfamily

The presence of multiple functional groups and stereocenters in complex carbohydrates makes them challenging targets for the organic chemist.

Glycosyltransferases were initially considered to be specific for a single glycosyl donor and acceptor, which led to the one enzyme-one linkage concept. Subsequent observations have refuted the theory of absolute enzymatic specificity by describing the transfer of analogs of some nucleoside mono- or diphosphate sugar donors.
