PtSABATH1, also named PtIAMT1, can catalyze the formation of methyl indole-3-acetate (MeIAA) using SAM as a methyl donor and indole-3-acetic acid (IAA) as a methyl acceptor. Enzyme PtSABATH1 does not show any activity towards substrates benzoic acid, jasmonic acid, salicylic acid, vanillic acid, nicotinic acid, coumalic acid, or trans-cinnamic acid. Compared with other Populus SABATH proteins (PtSABATH2, 3, 12, 17, 21 and 24 have very weak activities towards IAA), PtSABATH1 shows at least 40.5fold higher activity towards IAA
