Azides 79-84 acetylcholinesterase (Cartwright blood group) Homo sapiens 54-58 17034128-9 2006 All of these results, thus, imply that inside the AChE gorge, the azide group of 3 and the acetylene group of 4 always remain parallel, with the consequence that 1 is the only product. Azides 66-71 acetylcholinesterase (Cartwright blood group) Homo sapiens 50-54
