Modelling haem B and haem C using monomer descriptions from the Chemical Component Dictionary (CCD; Westbrook et al., 2015BB47). (a) Haem B (CCD identifier HEM). (b) Haem C (CCD identifier HEC) covalently bound to protein via cysteine thiols. Note that the wwPDB recommends against using the CCD component HEM for modelling haem C, which is found covalently linked to other components via thioether bridges. Also, the Fe atom should have charge +2 (unless bound to another molecule); standard representations are presented. Images were created using ChemDraw Professional 17.1.
