Abstract

Sulfitobacter is a bacterium recognized for its production of AMP-independent sulfite oxidase, which is instrumental in the creation of sulfite biosensors. This capability underscores its ecological and economic relevance. In this study, we present a newly discovered phage, Sulfitobacter phage vB_SupP_AX, which was isolated from Maidao of Qingdao, China. The vB_SupP_AX genome is linear and double-stranded and measures 75,445 bp with a GC content of 49%. It encompasses four transfer RNA (tRNA) sequences and 79 open reading frames (ORFs), one of which is an auxiliary metabolic gene encoding thioredoxin. Consistent with other N4-like phages, vB_SupP_AX possesses three distinct RNA polymerases and is characterized by the presence of four tRNA molecules. Comparative genomic and phylogenetic analyses position vB_SupP_AX and three other viral genomes from the Integrated Microbial Genomes/Virus v4 database within the Rhodovirinae virus subfamily. The identification of vB_SupP_AX enhances our understanding of virus-host interactions within marine ecosystems.
