3.1.1.7 additional information Mytilus galloprovincialis ChE degrades preferentially acetylthiocholine (AcSCh), followed by acetyl-beta-methylthiocholine (AbSCh) and propionylthiocholine (PrSCh), while butyrylthiocholine (BuSCh) is poorly hydrolysed. About 9% to 10% of the ChE activity observed, with AcSCh as substrate, is probably due to other esterases (CoEs) activity Mytilus galloprovincialis ?
