In silico description of cobalt and nickel assimilation systems in the genomes of methanogens.

ABSTRACT: Methanogens are a diverse group of organisms that can live in a wide range of environments. Herein, cobalt and tungsten assimilation pathways have proposed to be established in the genomes of Methanococcus maripaludies C5 and Methanosarcina mazei Go1, respectively. All of the proteins involved in the proposed pathways were identified from public domain databases and then complied manually to reconstruct the pathways. The function of proteins with unknown function was assigned by a combined prediction approach. Totally, 17 proteins were identified to cobalt transport and assimilation processes whereas 7 proteins reported to tungsten assimilation system. Phylogenetic analysis of this study revealed that heavy metal transporter of methanogens could be evolved from closely related members in t
