| Abstract: | The rational design of enzyme catalysts for chiral chemistry and of drugs which bind to proteins would be facilitated if rules for the recognition of one partner by the other could be formulated. This communication suggests and tests one generalization: arginine forms a tighter ion pair with a carboxylate group than does lysine and is always used for ion-pairs which are not broken during turnover in naturally-occurring enzymes. |
