1.B.86. The OmpO Outer Membrane Porin (OmpO) Family
Some members of the OmpO family of bacteria play roles in oxidative stress tolerance (Ku et al. 2023; Yang et al. 2025). This has been documented with Stenotrophomonas maltophilia KJ and Xanthomonas fragariae (see references cited above).
This family belongs to the: Outer Membrane Pore-forming Protein I (OMPP-I) Superfamily .
