Lysine as a heme iron ligand: A property common to three truncated hemoglobins from Chlamydomonas reinhardtii. Biochim Biophys Acta Gen Subj, 1862:2660-2673, 2018 Cited by PubMed Abstract: The nuclear genome of Chlamydomonas reinhardtii encodes a dozen hemoglobins of the truncated lineage. Four of these, named THB1-4, contain a single ~130-residue globin unit. THB1, which is cytoplasmic and capable of nitric oxide dioxygenation activity, uses a histidine and a lysine as axial ligands to the heme iron. In the present report, we compared THB2, THB3, and THB4 to THB1 to gain structural and functional insights into algal globins.
