Acetylcholinesterase from rat red cells and cholinesterase ofPseudomonas aeruginosa: Different types of inhibition by atropine

Abstract: SummaryThe inhibition by atropine of cholinesterase from PseUdomonas aeruginosa has been studied in parallel with the membrane bound acetylcholinesterase from rat red cells.Acetylcholinesterase of rat red cells, llke other animal cholinesterases, was competitively inhibited while the cholinesterase from Pseudomonas aeruginosa was partially non competitively inhibited by atropine. These results clearly indicated a different behavior of cholinesterase from Pseudomonasaeruginosain comparison with the enzyme of Ps… Show more

“…A standard protocol was followed to measure the activity of ChoE using ATCh, PTCh, or BTCh as substrates (12,61,62) with minor modifications. Assays were conducted at 22 °C in 100 mM sodium phosphate buffer (pH 7.0), 0.33 mM 5,5-dithiobis-(2-nitrobenzoic acid) for 3 min.…”

“…So konnte z. B. festgestellt werden, dass eine PLC und eine Phosphorylcholin-Phosphatase, dessen Genexpression durch Cholin induziert wird, eine entscheidende Rolle beim Infektionsprozess von P. aeruginosa spielen (Berka et al, 1981;Domenech et al, 1981;Berk et al, 1987;Domenech et al, 1991;Lisa et al, 1994b;Terada et al, 1999;Wieland et al, 2002;Wargo et al, 2011). Es wird vermutet, dass die Kopfgruppe des Phospholipids Phosphatidylcholin über die PLC abgespalten wird (Stinson und Hayden, 1979) und anschließend das entstehende Phosphorylcholin zu Cholin und einem Phosphat mittels einer Phosphorylcholin-Phosphatase gespalten wird (Garrido et al, 1990).…”
