Effect of different compounds on 1-aspartamido-beta-N-acetylglucosamine amidohydrolase from human liver.

چکیده
The effect of varous compounds on 1-aspartamido-beta-N-acetylglucosamine amidohydrolase (aspartylglucosylaminase, EC 3.5.1.26) was studied. N-Acetylcysteine inhibited the nezyme non-competitively (Ki 3.2 mM), whereas 3-hydroxybutanone inhibited competitively (Ki 4.1 mM). Methionine, isoleucine and cystathionine apparently enhanced the enzyme activity. The enzyme had a mol. wt. of 63000 as determined by gel filtration. The present studies differentiate between the aspartylglucosylaminase from human liver and that obtained from various other sources.

Purification and structure of human liver aspartylglucosaminidase.
We have recently diagnosed aspartylglucosaminuria (AGU) in four members of a Canadian family. AGU is a lysosomal storage disease in which asparagine-linked glycopeptides accumulate to particularly high concentrations in liver, spleen and thyroid of affected individuals. A lesser accumulation of these glycopeptides is seen in the kidney and brain, and they are also excreted in the urine. The alt...
متن کاملA di-N-acetylchitobiase activity is involved in the lysosomal catabolism of asparagine-linked glycoproteins in rat liver.
A perfused rat liver was used to study the effects of 5-diazo-4-oxo-L-norvaline on lysosomal glycoprotein catabolism. Addition of this compound (1.0 mM) to the perfusate reduced activity of beta-aspartyl-N-acetylglucosylamine amidohydrolase by 99% in 1 h. Treated livers were unable to completely degrade endocytosed N-acetyl[14C]glucosamine-labeled asialo-alpha 1-acid glycoprotein as evidenced b...

Four glycopeptides were isolated from desialized orosomucoid following digestion with Pronase and chromatography on sulfoethyl cellulose. The structure of the major glycopeptide was studied with sequential hydrolysis with /3galactosidase, /3-acetylglucosaminidase, and a-mannosidase, as well as by oxidation with periodate. Evidence for a glycosylamine type linkage between aspartic acid and acety...

Background: High level of blood cholesterol can cause diseases such as atherosclerosis, high blood pressure, cardiovascular diseases, and increase the chance of apoplexy and fatty liver. Unsaturated fatty acids play important roles in preventing cardiovascular diseases because they decrease total cholesterols and LDL-C in the blood. Objective: The study investigates some sterol compounds of Ira...
