Untersuchungen über esterspaltende Enzyme von Versuchstieren und Methoden zu ihrer routinemässigen Bestimmung, IV

Abstract: Kaninchenserum wurde mit Hilfe der Stärkebreielektrophorese über grosse Trennstrecken aufgetrennt, wobei 12 aromatische Ester hydrolysierende Enzyme isoliert wurden. Die Mehrzahl dieser Enzyme haben 2 Optima der Kettenlänge, denen stets unterschiedliche pH-Optima und ein unterschiedliches Verhalten gegen E 600 entsprechen. 10 der 12 Enzyme sind Arylesterasen (E.C. 3.1.1.2) und besitzen die Fähigkeit, kurzkettige Fettsäuren gegen langkettige um- zuestern. Die Enzyme sind weitgehend resistent gegen E 600; die be… Show more

“…However, it should be realized that human and rabbit plasma contain at least 12 different arylesterases (Pilz, 1964;Pilz et al, 1968), most of them probably not related to cholesterol metabolism. As only one of the esterases (Est-2) in the zymogram of rabbit plasma has been found to predict the serum cholesterol response to dietary cholesterol, it would be desirable to study and measure the plasma esterases separately.…”

“…Until now, the best separation of the serum aryl esterases of rabbits was performed by Pilz et al (1968), using preparative starch-"brei" electrophoresis. They identified ten different arylesterases (substrates: phenyl and /?-naphtyl esters), which were not inhibited by paraoxon.…”

“…In individual random-bred rabbits we did not find an association between initial plasma total esterase activity and the subsequent plasma cholesterol response to cholesterol feeding . This may be explained by the facts that random-bred rabbits vary considerably in their plasma-esterase zymograms (Van Zutphen, unpublished) and that rabbit plasma contains at least 12 different arylesterases (Pilz et al, 1968). On the other hand, only one of the esterases (Est-2) in the zymogram of rabbit plasma has been found to correlate with the plasma cholesterol response to dietary cholesterol (Van Zutphen and Fox, 1977).…”
