Functional characterization of a DNA-dependent AAA ATPase in SimranZ1, a F cluster mycobacteriophage

Abstract

Mycobacteriophages are viruses of Mycobacterium spp. with promising diagnostic and therapeutic potential. Phage genome exploration and characterization of their proteomes are essential to gain a better understanding of their role in phage biology. So far, about 2014 mycobacteriophages have been genomically defined and 1563 phage protein families (phamilies) are identified. However, the function of only a fraction (about 15%) is known and a majority of ORFs in phage genomes are hypothetical proteins. In this study, from the annotated genome of a F1 cluster mycobacteriophage SimranZ1, a putative AAA ATPase (Gp65, Pham 9410) is characterized as a DNA-dependent ATPase.
