本酶催化的反应为(1) Iron(III)-[Diglucosyl-Enterobactin] Complex + H2O = Iron(III)-[Salmochelin S2] Complex;;(2) Iron(III)-[Monoglucosyl-Enterobactin] Complex + H2O = Iron(III)-[Monoglucosyl-(2,3-Dihydroxybenzoylserine)3] Complex;;(3) Iron(III)-[Salmochelin S2] Complex + H2O = Iron(III)-[Diglucosyl-(2,3-Dihydroxybenzoylserine)2] Complex + N-(2,3-Dihydroxybenzoyl)-L-Serine;;(4) Iron(III)-[Salmochelin S2] Complex + H2O = Iron(III)-[Salmochelin S1] Complex + Salmochelin SX;;(5) Iron(III)-[Monoglucosyl-(2,3-Dihydroxybenzoylserine)3] Complex + H2O = Iron(III)-[Salmochelin S1] Complex + N-(2,3-Dihydroxybenzoyl)-L-Serine;;(6) Iron(III)-[Diglucosyl-(2,3-Dihydroxybenzoylserine)2] Complex + H2O = Iron(III)-[Salmochelin SX] Complex + Salmochelin SX，系统名称为Iron(III)-Salmochelin Complex Hydrolase，这种细菌酶存在于致病性沙门氏菌属、尿路致病性和禽致病性大肠杆菌菌株以及某些克雷伯菌属菌株中。该酶作用于铁(III)结合的肠杆菌素和称为沙门菌素的 C-葡萄糖基化衍生物。与 EC 3.1.1.107（脱辅基-沙门菌素酯酶（IroE））不同，IroD 优先以铁(III)结合的铁载体为底物，并被认为在铁-铁载体复合物输入细胞后起作用。它催化几个水解反应，产生铁(III)-[N-(2,3-二羟基苯甲酰)-L-丝氨酸]复合物和沙门菌素 SX 的混合物。
