Dual roles of Bradyrhizobium japonicum nickelin protein in nickel storage and GTP-dependent Ni mobilization.

Journal of bacteriology - 1 Mar 2000

Olson J W, Maier R J

Abstract excerpt

The hydrogenase accessory protein HypB, or nickelin, has two functions in the N(2)-fixing, H(2)-oxidizing bacterium Bradyrhizobium japonicum. One function of HypB involves the mobilization of nickel into hydrogenase. HypB also carries out a nickel storage/sequestering function in B. japonicum, binding nine nickel ions per monomer. Here we report that the two roles (nickel mobilization and storage) of HypB can be...
