Antibiotic resistance-bearing Tn21-like transposon of pAKD1. This 11,920-bp transposon disrupted the resolvase (parA), resulting in separation of the 3′ and 5′ ends. It consists of transposition genes tnpA and tnpR, a class 1 integron, IS6100, a sulfate transporter (sulP), and a universal stress protein (uspA). The integron has an integrase (int1), an aminoglycoside adenyltransferase gene (aadA) encoding resistance to streptomycin and spectinomycin, a sulfonamide resistance gene (sul1), and a putative acetyltransferase (orf5).
