... determined that AOP2 was absent from porcine, murine, and human plasma (data not shown). To gain insight into how AOP2 interacts with itself or other proteins, RBC stroma proteins were examined using native ... hemoglobin in RBC lysate. Cysteine 47 is essential for AOP2-heme binding The binding of AOP2 and heme led us to investigate the mechanism by which AOP2 binds to heme. All peroxir...

Remaining ... instances subsumed by candidate conceptual instance c. Intuitively, better candidate conceptual in- stances are those that subsume both many in- stances and other candidate conceptual...
