A joint agreement to use only the words "dratted" and "dastardly" will soon mend the relationship.
This is followed by the draT and draG genes (AFE1524, AFE1525) that encode a dinitrogen-reductase ADP-D-ribosyltransferase and a ADP-ribosyl-[dinitrogen reductase] hydrolase, respectively.
The second checkpoint occurs upon reversible inactivation of nitrogenase by dinitrogenase reductase ADP-ribosyltransferase (DraT) and dinitrogenase reductase glycohydrolase (DraG) [ 29].
In R. rubrum the regulatory enzymes dinitrogenase reductase ADP-ribosyl transferase (DRAT) and dinitrogenase reductase-activating glycohydrolase (DRAG) regulate nitrogenase activity by reversible ADP-ribosylation of NifH [ 28, 29].
Moreover, although nitrogenase on-off switching was previously reported [ 13], DraT and DraG (known to control nitrogenase ADP ribosylation) have not been found in A1501, suggesting that it possesses an inactivation mechanism different from that reported in Rhodospirillum rubrum [ 37], Azoarcus [ 38], and A. brasilense [ 39].
I say drat, egad and pish (or one of those other crosswordy exclamations that have saved me in a tight corner) to blasted rules!
It is reasonable to assume that other specific ARTs such as DRAT, T4 and CT undergo similar extensive interactions with their target proteins.
He confounded censors by substituting "Godfrey Daniel!", "Mother of Pearl!", and "Drat!" for harsher expletives, and he raised the ire of parents by exhibiting an open disdain for children and dogs that nearly matched his fondness for alcohol.
On the other hand, Azospirillum sp. B510 and A. brasilense have the aerC gene between the nifHDK and nifENX operons and the draG and draT genes in the upstream region of the nifH gene, features not shared with the nif cluster of A. amazonense.
The Guardia Civil, the Spanish Interior Ministry's police force, has once again made a lot of trouble and, drat, work for the country's sports and judicial authorities.
