Ferrochelatase (EC 4.99.1.1), the terminal enzyme of the heme biosynthetic pathway, catalyzes Fe(2+) chelation into protoporphyrin IX. Resonance Raman and UV-vis absorption spectroscopies of wild-type and engineered variants of murine ferrochelatase were used to examine the proposed structural mechanism for iron insertion into porphyrin. The recombinant variants (i.e., H207N and E287Q) are enzy...

The pursuit for drugs that inhibit cyclin-dependent kinases (CDKs) has been an intense area of research for more than 15 years. The first-generation inhibitors, Flavopiridol and CY-202, are in late-stage clinical trials, but so far have demonstrated only modest activity. Several second-generation inhibitors are now in clinical trials. Future approaches to determine clinical benefit need to inco...
