*1.B.39.1.1









Outer membrane porin, OmpW.  Involved in paraquot efflux (Gil et al. 2007). OmpW also participates in the efflux of EmrE-specific substrates across the OM (Beketskaia et al. 2014). The 3-d structure is available (PDB#2F1C).

OmpW of Salmonella typhimurium
*1.B.39.1.2









OCT plasmid-encoded AlkL outer membrane cation-selective porin, (probably transports alkanes) (van Beilen et al., 1992).  Has been used for the uptake of dodecanoic acid methyl ester (DAME) in E. coli for the production of  12-aminododecanoic acid methyl ester (ADAME), a building block for the high-performance polymer Nylon 12 (Ladkau et al. 2016).
