Heterologous Expression of the Desulfovibrio
gigas [NiFe] Hydrogenase in Desulfovibrio
fructosovorans MR400
hynABC to express the heterologous cloned [NiFe]
hydrogenase of Desulfovibrio gigas was investigated. The
[NiFe] hydrogenase operon from D. gigas,
hynABCD, was cloned, sequenced, and introduced into
D. fructosovorans MR400. A portion of the recombinant
heterologous [NiFe] hydrogenase was totally matured, exhibiting
catalytic and spectroscopic properties identical to those of the native
D. gigas protein. A chimeric operon containing
hynAB from D. gigas and hynC from
D. fructosovorans placed under the control of the D. fructosovorans hynAp promoter was constructed and expressed in D. fructosovorans MR400. Under these conditions, the same
level of activity was obtained as with the D. gigas
hydrogenase operon.
