Explain How Transcriptional Control by the NrpR Protein of the Archaeon

question 16

Essay

Explain how transcriptional control by the NrpR protein of the archaeon Methanococcus maripaludis is similar to transcriptional control in bacteria.
It is known that 2-oxoglutarate (2OG)is used by cells as an indicator of nitrogen deficiency. Based on what you know about effector molecules in bacterial operons, how would 2OG behave in
M. maripaludis (as an inducer, a corepressor, etc.)and what effect would this molecule have on NrpR binding?
