I totally agree (with Lpezzee, Boghog, CopperKettle) that the "Cholinesterase enzyme" wiki.Page title should be "Cholinesterase Enzymes", containing all of the common conformational, reactive etc. features of the iso-enzymes of this class while only the specific differences between AChE, BChE, PChE and whatever else will be discovered out there should be reserved to be represented on those respective pages.
