General Information

EC Number General Information Comment Organism
1.12.7.2 malfunction all ehb mutants have severe growth deficiencies except the DeltaehbO::pac strain: The membrane-spanning ion translocator (DELTAehbF) and the large hydrogenase subunit (DELTAehbN) deletion strains display the severest growth defects. The DELTAehbN mutant strain is sensitive to growth inhibition by aryl acids Methanococcus maripaludis
