== Publication Abstract from PubMed ==
The 1.70 A-resolution X-ray crystal structure of the green pigment occasionally present in nitrite-cured meat reveals a regiospecific nitration of the heme at the 2-vinyl position; the regiospecificity is favored on steric grounds, and results in movement of the 2-nitrovinyl moiety into the plane of the 24-atom heme macrocycle.

Unveiling the three-dimensional structure of the green pigment of nitrite-cured meat.,Yi J, Richter-Addo GB Chem Commun (Camb). 2012 May 4;48(35):4172-4. Epub 2012 Mar 20. PMID:22430128<ref>PMID:22430128</ref>
