Function

[MBHL_CUPNH] This enzyme recycles the H(2) produced by nitrogenase to increase the production of ATP and to protect nitrogenase against inhibition or damage by O(2) under carbon- or phosphate-limited conditions. [MBHS_CUPNH] This enzyme recycles the H(2) produced by nitrogenase to increase the production of ATP and to protect nitrogenase against inhibition or damage by O(2) under carbon- or phosphate-limited conditions.

4ttt, resolution 1.72Å
