Early effects of aminonucleoside on enzymes in the Golgi apparatus of rat liver. 1975

E Katona, and M A Moscarello

Rats were injected with a single intravenous dose of aminonucleoside (AMN) and sacrificed 1-48 h later. The activity of several enzymes was assayed in the Golgi apparatus isolated from the liver. Galactosyltransferase activity showed little changes after the AMN, but both acid (EC 3.1.3.2) and alkaline phosphatase (EC 3.1.3.1) activities increased within the first hour and reached control levels only 5-24 h later. Thiamine pyrophosphatase and arylsulfatase A (EC 3.1.6.1) activities also increased and stayed at higher levels for the duration of the experiment. Arylsulfatase B (EC 3.1.6.1) activity decreased shortly after the AMN but later increased to above control levels. These findings support earlier results in which liver ultrastructural and biochemical changes were observed early before renal lesions and proteinuria.

D002553	Cerebroside-Sulfatase	An enzyme that catalyzes the hydrolysis of cerebroside 3-sulfate (sulfatide) to yield a cerebroside and inorganic sulfate. A marked deficiency of arylsulfatase A, which is considered the heat-labile component of cerebroside sulfatase, has been demonstrated in all forms of metachromatic leukodystrophy (LEUKODYSTROPHY, METACHROMATIC). EC 3.1.6.8.	Arylsulfatase A,Sulfatidate Sulfatase,Cerebroside Sulfatase,Sulfatase, Sulfatidate
D002803	Chondro-4-Sulfatase	An enzyme from the sulfuric ester hydrolase class that breaks down one of the products of the chondroitin lyase II reaction. EC 3.1.6.9.	Chondro 4 Sulfatase
D005700	Galactosyltransferases	Enzymes that catalyze the transfer of galactose from a nucleoside diphosphate galactose to an acceptor molecule which is frequently another carbohydrate. EC 2.4.1.-.	Galactosyltransferase
D006056	Golgi Apparatus	A stack of flattened vesicles that functions in posttranslational processing and sorting of proteins, receiving them from the rough ENDOPLASMIC RETICULUM and directing them to secretory vesicles, LYSOSOMES, or the CELL MEMBRANE. The movement of proteins takes place by transfer vesicles that bud off from the rough endoplasmic reticulum or Golgi apparatus and fuse with the Golgi, lysosomes or cell membrane. (From Glick, Glossary of Biochemistry and Molecular Biology, 1990)	Golgi Complex,Apparatus, Golgi,Complex, Golgi
D000135	Acid Phosphatase	An enzyme that catalyzes the conversion of an orthophosphoric monoester and water to an alcohol and orthophosphate. EC 3.1.3.2.	Acid beta-Glycerophosphatase,Acid beta Glycerophosphatase
D000469	Alkaline Phosphatase	An enzyme that catalyzes the conversion of an orthophosphoric monoester and water to an alcohol and orthophosphate. EC 3.1.3.1.
