## TL;DR

This paper presents the complete genome sequences of two Streptomyces-infecting bacteriophages, HazuAndZazu and Tubberson, including their genetic features and classification.

## Contribution

The study provides novel genome sequences and annotations for two Streptomyces phages, including the discovery of an immunity mechanism in Tubberson.

## Key findings

- HazuAndZazu and Tubberson are Caudoviricetes with siphoviral morphology infecting Streptomyces species.
- Tubberson's genome includes an annotated immunity mechanism.
- The phages have distinct GC contents and genome lengths.

## Abstract

Bacteriophages HazuAndZazu and Tubberson, belonging to the BI1 and BC1 subclusters, are Caudoviricetes with a siphoviral morphology that infect Streptomyces species. They have GC contents of 59.5% and 71.5%, and genomes 55,823 and 39,028 bp long, respectively. Annotation of cluster BC phage Tubberson includes an immunity mechanism.
