The circle in the gene cassette (GC) structure represents the attC site, where the base in red indicates a variant in the conserved region. Nucleotide sequences with asterisks indicate the inverted repeats. Samples are named on the basis of the abbreviation for the WWTPs and sample types. For example, “QPE” refers to the effluent sample (E) from of Qianpu (QP) wastewater treatment plant. LY, Longyan; JM, Jimei.
