vBYpM50_00004	ENOG4105ED4	portal protein
vBYpM50_00022	ENOG4108X9F	tail fiber protein
vBYpM50_00031	ENOG4105ZTC	transcriptional activator, Ogr delta
vBYpM50_00032	ENOG4105C13	Site-specific tyrosine recombinase, which acts by catalyzing the cutting and rejoining of the recombining DNA molecules. The XerC-XerD complex is essential to convert dimers of the bacterial chromosome into monomers to permit their segregation at cell division. It also contributes to the segregational stability of plasmids (By similarity)
