Purified protein samples were separated by 2-DE with 17 cm IPG strips, and the protein spots were detected by fast silver staining. Six protein spots were randomly excised from the silver stained gel for primary analysis by MALDI-TOF MS. Four proteins were identified, and they were 1-aminocyclopropane-1-carboxylate synthase 2, ribulose-1, 5-bisphosphate carboxylase/oxygenase large subunit, F11O4.2 and Rubisco small subunit.

Therefore, the metabolic pathway from soybean oil to erythromycin was presumed as follows: soybean oil is metabolized into TCA pathway to generate much α ketoglutaric acid and then generate succinyl CoA by strengthening TCA pathway, and the methylmalonyl CoA is formed from succinyl CoA by isomerization. Finally, methylmalonyl CoA can be used as the precursor for the biosynthesis of erythromycin.

推测豆油经过红色糖多孢菌代谢后进入红霉素合成的一条可能途径：豆油经过代谢后进入TCA循环，并强化了TCA循环的通量，产生了大量α酮戊二酸，再生成琥珀酰CoA，琥珀酰CoA在甲基丙二酰CoA异构酶的作用下生成甲基丙二酰CoA作为红霉素合成的前体。
