Abstract
We have investigated the binding of porcine pancreatic phospholipase A2 (PA2) to n-hexadecylphosphocholine (C16PN) micelles using optical detection of triplet state magnetic resonance (ODMR) spectroscopy. The zero field splittings (zfs) of the single Trp3 residue undergo significant changes upon binding of PA2 to C16PN micelles. Zfs titrations of PA2 vs
