Annotation of Two Soil Mycobacteriophages: JacoRen57 and DrLupo

We discovered two novel Mycobacteriophagesfrom soil samples. JacoRen57 is a singleton, most closely related to cluster AB phages. DrLupois a member of the rare H2 sub-cluster containing only one other member. Both phages exhibit a siphoviridaemorphotype, double-stranded DNA genome, and a non-contractile tail. The genome of JacoRen57 is composed of 52,411 base pairs with a 56.7% GC content and includes genes and plaque morphology that suggest a lytic life cycle. The genome is organized according to the following order from the left to right arm: 33 forward genes followed by 16 reverse genes and 24 forward genes. We identified functions for 33 of the 73 protein coding genes using bioinformatics software. The 70,030 base-pairgenome of DrLupohas a 57.5% GC content and contains genes that support a lytic life cycle. We identified 110 forward genes and assigned functions to 25 of them
