[ccp4bb] unknown density

2009-04-08 Thread Rajan
Dear all, i am working on a structure of M.tb, solved at 2.18 A. In my structure there is a density near to the active site and we modelled it as a malonate (C3 O4 H2) molecule acorrding to the density, which was not used in any of our buffer except we used 10 mM DTT, 1.6 M Ammonium sulphate, 100

Theoretically, citric acid can decompose into beta-ketoglutaric acid, and the latter may decarboxylate into malonic acid... Not sure if this happens in aqueous solutions, but if your citrate had malonate contamination and your enzyme prefers malonate to anything else - that's where it may have
