Abstract
Enzimi su katalizatori u biološkim sustavima. Ubrzavaju reakcije snižavanjem energije aktivacije. Gotovo svi poznati enzimi su proteini. Najvažniji dio enzima je aktivno mjesto u kojem se odvija specifiĉna reakcija. Butirilkolinesteraza (BuChE) pripada skupini kolinesteraza odnosno estereaza. Esteraze spadaju u grupu hidrolaza. BuChE inaktivira neurotransmiter acetilkolin (ACh) i kao takva je postala terapeutski cilj u poodmaklim fazama Alzheimerove bolesti. Kao izvor enzima korištena je butirilkolinesteraza (BuChE) iz seruma konja, a kao supstrat enzima korišten je butiriltiokolin jodid (BuTChI). Kao inhibitor enzima korišten je α-terpinolen. Iz Lineweaver-Burk, Hanes-Wolf i Eisenthal – Cornish-Bowden prikaza te izraĉunatih postotaka inhibicije zakljuĉeno je da α-terpinolen pokazuje sposobnost inhibicije enzima BuChE. Kako se povećava koncentracija α-terpinolena povećava se i postotak inhibicije. Također je zakljuĉeno da se radi o inhibiciji miješanog tipa te su određeni odgovarajući kinetiĉki parametri KM, Vmax, KMapp, Vmaxapp, KI i KI'.
Abstract (english)
Enzymes are catalysts in biological systems. Accelerate reactions by lowering the activation energy. Nearly all known enzymes are proteins. The most important part of the enzyme is their active site where reactions take place. Butyrylcholinesterase (BuChE) belongs to a class of cholinesterase or esterase. Esterases belong to the group of hydrolases. BuChE inactivates the neurotransmitter acetylcholine (ACh) and as such has become a therapeutic target in later stages of Alzheimer's disease. Butyrylcholinesterase (BuChE) enzyme was obtained from the horse serum, and as a substrate of the enzyme was used butyrylthiocholine iodide (BuTChI). The enzyme used was α-terpinolene. From Lineweaver-Burk, Hanes-Wolf and Eisenthal - Cornish-Bowden display and calculated the percent inhibition was concluded that α-terpinolene shows the ability to inhibit the enzyme BuChE. α-Terpinolene inhibits BuChE in dose dependent manner. It was also concluded that it is a mixed type inhibition and certain corresponding kinetic parameters KM, Vmax, KMapp, Vmaxapp, KI and KI'.
