Distribution of Hydrogenases in Cyanobacteria: A Phylum-Wide Genomic Survey.

ABSTRACT: Microbial Molecular hydrogen (H₂) cycling plays an important role in several ecological niches. Hydrogenases (H₂ases), enzymes involved in H₂ metabolism, are of great interest for investigating microbial communities, and producing BioH₂. To obtain an overall picture of the genetic ability of Cyanobacteria to produce H₂ases, we conducted a phylum wide analysis of the distribution of the genes encoding these enzymes in 130 cyanobacterial genomes. The concomitant presence of the H₂ase and genes involved in the maturation process, and that of well-conserved catalytic sites in the enzymes were the three minimal criteria used to classify a strain as being able to produce a functional H₂ase. The [NiFe] H₂ases
