Repeated intergenic regulatory sequences have been identified in phages that infect most all of the SEA PHAGES hosts. These are recognized as short conserved regions that branch from one spot when two or more phages are loaded in Phamerator. Usually these are 25-50bp. FK phages have a HUGE region of >20 genes that have one of largest areas and longest repeats (See attachment). It is key to NOT change start calls for genes that are not the LORF in these regions and make sure that these sequences remain upstream of the start codon.
