Complete genome sequence of Brachybacterium sp. GU-2 (Actinomycetota), isolated from the massive coral Porites lobata .

Brachybacterium sp. GU-2 was isolated from the hard coral Porites lobata found in Apra Harbor, Guam, Micronesia. This genome sequence will be beneficial to understand the role of actinomycetes in coral holobionts. The Brachybacterium genome contains several gene clusters for bioactive compounds, including antibiotics.
