Here, we report the restriction modification system of Nostoc punctiforme ATCC 29133, along with its methylated genome sequence, under contrasting nitrate availability. Generated methylation profiles revealed increased methylation for key enzymes of assimilatory nitrate reduction, suggesting that Nostoc punctiforme employs DNA methylation to regulate its nitrogen metabolism.
