MUTYH and infection: The four unique proteins which showed up in the stress without pathogen infection attaching to fengycin were (1) A/G-specific adenine DNA glycosylase; (2) flavin monooxygenase-like protein; (3) inner membrane protein yieG; and (4) ribosome-binding ATPase YchF, which have functions in base-excision repair, the oxidation-reduction process, transport, and the response to oxidative stress, respectively, through biological processes [29].
