Dear Adriana, this depends on the enzyme i.e. does your enzyme hydrolyse the alpha-beta or beta-gamma bond? If it hydrolyses the beta-gamma bond, options mentioned are indeed: -AMPPNP (Adenylyl-imidodiphosphate) -AMPPCP(β,γ-Methyleneadenosine 5′-triphosphate)* *-AMPPP(S) (ATP-γ-S) -ADP-BeFx -

Hi, one word of caution with Metal fluoride complexes. Though they can provide valuable inside in the reaction mechanism, even better than some ATP-analogues, one has to be careful what metal to use to get the right complex. See review below, which summarises the problems which can occur, es

Hi, ATPgS is an option, but it is slowly hydrolysable, so depending on your enzyme, it might not be the best one to use. Cheers, Alexandra On Tue, May 2, 2017 at 2:56 PM, Aaron Thompson wrote: > ATP-gamma-S is another option. There are 123 public structures > containing this ligand (ligand I

ATP-gamma-S is another option. There are 123 public structures containing this ligand (ligand ID AGS). Cheers, Aaron On Tue, May 2, 2017 at 11:42 AM, Kevin Jude wrote: > ADP-BeFx and ADP-AlFx (the latter mimics a dissociative transition state). > The fluoride compounds can be made by mixing

ADP-BeFx and ADP-AlFx (the latter mimics a dissociative transition state). The fluoride compounds can be made by mixing BeCl2 or AlCl3 with excess NaF and then used at say a 3:1 excess over ADP. Be sure to dissolve the chloride compounds in a fume hood! Also ADP-VO4, which can be prepared as descr
