DOES THE OBSERVATION OF NONCOVALENT COMPLEXES BETWEEN BIOMOLECULES BY ELECTROSPRAY-IONIZATION MASS-SPECTROMETRY NECESSARILY REFLECT SPECIFIC SOLUTION INTERACTIONS
Electrospray ionisation mass spectrometry is used to observe complexes formed between porcine pancreatic elastase (PPE) and its peptidic substrates and products; analogous complexes are observed between PPE and the enantiomers of the substrates and products.
