3.2.2.24 | ADP-D-ribosyl-(dinitrogen reductase) component of nitrogenase complex |
enzyme is sensitive to the redox-state of the (Fe4S4) cluster of substrate protein, having less than 2% of activity with oxidized Fe protein compared to reduced Fe protein |

3.2.2.24 | ADP-D-ribosyl-(dinitrogen reductase) component of nitrogenase complex + H2O |
ADP-ribosylation of initrogenase reductase (NifH) occurs in response to addition of ammonium to the extracellular medium and is mediated by dinitrogenase reductase ADP-ribosyltransferase (DraT) and reversed by dinitrogenase reductase glycohydrolase (DraG). The PII protein GlnZ is implicated in regulation DraG. DraG binds to both the uridylylated and deuridylylated forms of GlnZ |

3.2.2.24 | ADP-D-ribosyl-(dinitrogen reductase) component of nitrogenase complex + H2O |
nitrogenase activity in Rhodospirillum rubrum is post-translationally regulated by DRAG (dinitrogenase reductase glycohydrolase) and DRAT (dinitrogenase reductase ADP-ribosylation transferase). When a sudden increase in fixed nitrogen concentration or energy depletion is sensed by the cells, DRAG is inactivated and DRAT activated |
