Publication Abstract from PubMed Heme post-translational modification plays a key role in tuning the structure and function of heme proteins. We herein report a novel tyrosine-heme covalent CO bond in an artificially produced sperm whale myoglobin (Mb) mutant, F43Y Mb, which formed spontaneously in vivo between the Tyr43 hydroxy group and the heme 4-vinyl group. This highlights the diverse chemistry of heme post-translational modifications, and lays groundwork for further investigation of the structural and functional diversity of covalently-bound heme proteins.
