The rhdA gene of Azotobacter vinelandii codes for RhdA, a rhodanese-domain protein with an active-site loop structure which has not currently been found in proteins of the rhodanese-homology superfamily. Considering the lack of information on the functional role of the ubiquitous rhodaneses, in the present study we examined the in vivo functions of RhdA by using an A. vinelandii mutant strain (...
