Neuronal NO synthase (nNOS) was discovered recently to interact specifically with the protein
PIN
(protein inhibitor of nNOS) [Jaffrey, S.R. and Snyder, S.H. (1996) Science 274, 774-777]. We have studied the effects on pure NOS enzymes of the same GST-tagged
PIN
used in the original paper. Unexpectedly, all NOS isoenzymes were inhibited. The IC50 for nNOS was 18 +/- 6 microM GST-
PIN
with 63 nM nNOS after 30 min at 37 degrees C. Uncoupled NADPH oxidation was inhibited similarly, whereas
cytochrome c reductase
activity, the K(M) for L-arginine, and dimerization were unaffected. We reconsider the physiological role of
PIN
in the light of these results.
