Genome map of the Vibrio phage ϕpp2. Green arrows indicate the genes matched to both Enterobacteria phage T4 and Vibrio phage KVP40. Yellow ticks on the circle indicate that the genes fitted to KVP40 only while the yellow triangle indicates the absent site for KVP40.0146 HE gene. Purple represents that the genes only aligned well with T4. The cyan is for one gene matched to GTP cyclohydrolase I from Bdellovibrio bacteriovoru HD100, Vibrio angustu S14, and Cytophaga hutchinsonii ATCC 33406. Red bars with the number indicate the PEG numbers of potential HE.
