Alternative entrances into the acetylcholinesterase active site
Original language description
Back door to the active site of acetylcholinesterase (AChE) and its involvement in the catalytic cycle of this enzyme are a really controversial subject. The back door could explain the contrast of a very high AChE catalytic efficiency and the narrow andlong access to the active site located in the middle of the protein. Back door could facilitate the diffusion of reaction products - choline or acetic acid after the cleavage of acetylcholine. Back door was seen only in a molecular dynamics of AChE, butfor a very short times and its existence was not confirmed experimentally. Herein we present a molecular dynamics of AChE, where the back door opening appears on a nanosecond time scale. We also present a molecular dynamics of AChE, where the back doordo not open at all, or where large conformational changes of AChE omega loop occur instead of back door opening events.
