FIGURE 3.
(A) Multiple sequence alignment of L1 and L2 motif of the [NiFe] hydrogenase large subunit of the different Kyrpidia species and strains. (B) Gene arrangement of the hydrogenases in different Kyrpidia isolates. Encoded proteins are colored as follows: green = large subunit, blue = small subunits, yellow = (putative) maturation proteins, orange = accessory proteins, purple = nickel transporter, pink = FeS cluster protein, dark purple = TTP repeat domain protein and dark green = NHL repeat domain protein.
