Ribosome hibernation promotion factor from Synechococcus sp. (strain ATCC 27264 / PCC 7002 / PR-6) was studied. It might modulate either transcription and/or translation. After the third iteration hit list was stabilised. The vast majority of proteins in the output involved in transcription regulation.
