Fig 7. Correlation plot between the ν(Fe-C) and ν(C-O) frequencies for ferrous-CO complexes of Cr-TrHb1-1, Cr-TrHb1-2, and Cr-TrHb1-4, compared with class 2 TrHbs from Bacillus subtilis (Bs-TrHb2) [40], Mycobacterium tuberculosis (Mt-TrHb2) [41], Pseudoalteromonas haloplanktis (Ph-TrHb2) [31], and Thermobifida fusca (Tf-TrHb2) [30].
