Abstract excerpt
In subunit I (FixN) of the Bradyrhizobium japonicum cbb3-type oxidase, only five instead of the normal six strictly conserved histidines (H) could be unambiguously assigned as the putative heme or copper ligands. The ambiguity concerned H43 or H131 as the presumptive N-terminal ligands of the low...
