Separation of N-Acetyl-alpha-Glucosaminidase and N-Acetyl-alpha-Galactosaminidase from Ox Spleen. Cleavage of the O-Glycosidic Linkage between Carbohydrate and Polypeptide in Ovine and Bovine Submaxillary Glycoprotein by N-Acetyl-alpha-Galactosaminidase

Histochemical studies on N-acetyl-beta-galactosaminidase in the ovary of sexually mature women.

1) The distribution of ƒÀ-GA was quite similar to that of ƒÀ-GL, but the activity of ƒÀ-GA was lower than that of ƒÀ-GL 2) Although no activity of ƒÀ-GA or ƒÀ-GL could be detected in primary follicles, some activity appeared in the theca interna layer of the developing follicles, and the activity increased as the follicles enlarged. However, no activity was found in the granulosa layer. 3) The ...

Is urinary N-acetyl-beta-D-glucosaminidase a marker of urological abnormality in children?

  Abstract   Background: Hydronephrosis is the most common congenital condition that is detected   by prenatal ultrasonography. Moreover, the widespread use of prenatal ultrasonography   results in an increased recognition of fetal hydronephrosis. Prenatal hydronephrosis   is diagnosed at an incidence of 1:100 to 1:500 by ultrasonographic studies. The presence of hydronephrosis is not synonymou...

Subcellular localization of the UDP-N-acetyl-D-galactosamine: polypeptide N-acetylgalactosaminyltransferase-mediated O-glycosylation reaction in the submaxillary gland.

Addition of N-acetylgalactosamine to threonine and serine is the first step in the synthesis of O-glycosidically linked oligosaccharides. A UDP-N-acetyl-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase (EC 2.4.1.41) from porcine submaxillary glands was recently purified to electrophoretic homogeneity, and polyclonal antibodies against the purified transferase were raised. Immunoblo...

Studies on glucosaminidase; N-acetyl-beta-glucosaminidase in rat kidney.

Studies on glucosaminidase. 2. Substrates for N-acetyl-beta-glucosaminidase.

the oxygen uptake and acetoacetate oxidation when added alone or with fumarate, but not in the presence of a-oxoglutarate. The reasons for these differences are discussed. Anaerobically, relatively slight inhibitions of the reduction of acetoacetate were observed. 6. The oxidation of L( + )-p-hydroxybutyrate is inhibited by dinitrophenol, whereas that of the D(-)-form is not. This is related to...
