Alteration of N-acetylglucosaminyltransferases in pancreatic carcinoma

Glycoconjugate Journal, 1998
The activities of three N-acetylglucosaminyltransferases (GnT III, GnT IV and GnT V) were determined in 10 samples of pancreatic carcinoma (PCa) and compared with those in 9 samples of normal pancreatic tissue (NP). It was found that the specific activities of GnT III, GnT IV and GnT V increased in all of the PCa samples.

N-Acetylglucosaminyltransferase-II

2002
The synthesis of complex N-glycans can be divided into three distinct stages. The first stage occurs primarily in the cytoplasm and rough endoplasmic reticulum, and involves the synthesis of Glc3Man9GlcNAc2-pyrophosphate-dolichol. The second stage begins with the transfer of GlcP3Man9GlcNAc2 from Glc3Man9GlcNAc2-pyrophosphate- dolichol to an Asn ...

β3-N-Acetylglucosaminyltransferase (iGnT)

2002
β3-N-Acetylglucosaminyrtransferase, i-extension enzyme (iGnT), is a glycosyltransferase that catalyzes the transfer of GlcNAc from UDP-GlcNAc to Gal in the Galβ1-4Glc(NAc) structure with β1,3-linkage. In N-glycans, the addition of β1,3- linked GlcNAc is usually followed by galactosylation by β1,4-galactosyltransferase I, the predominant member of the ...

β6-N-Acetylglucosaminyltransferase (IGnT)

2002
I-branching β6-N-acetylglucosaminyltransferase (IGnT) is a glycosyltransferase that catalyzes the transfer of GlcNAc from UDP-GlcNAc to β1,4-linked Gal residue in a linear poly-N-acetyllactosamine, ±Galβ1-4GlcNAcβ1-3Galβ1-4Glc(NAc)-R, forming ±Galβ1-4GlcNAcβ1-3(GlcNAcβ1-6)Galβ1-4Glc(NAc)-R.

β3-N-Acetylglucosaminyltransferase (Fringe)

2002
Fringe provides a clear example of the role that carbohydrate modifications can play in regulating signal transduction events. Fringe was originally identified for its role in dorsal/ventral boundary formation during Drosophila wing development (Irvine and Wieschaus 1994).

Core 2 β6-N- Acetylglucosaminyltransferase-II

2002
Core 2 β6-N-acetylglucosaminyltransferase-II (Core2GlcNAcT-II) is unique in having all of the core 2, core 4, and I branching activities (Yeh et al. 1999). Core2, core4, and I branching activities are related to each other, but distinguished by substrate acceptors (Fig. 1).

Chemical Modification of N-acetylglucosaminyltransferases.

Sheng wu hua xue yu sheng wu wu li xue bao Acta biochimica et biophysica Sinica
The essential groups of three N-acetylglucosaminyltransferases (GnTs) of rat kidney were studied by using chemical modification and substrate protection methods. It was found that the amino and indolyl groups were the common essential groups of GnT-III, GnT-IV and GnT-V.
