1.B.25.1.1
OprD2; OccD1; porin D transports cationic amino acids, peptides and other compounds: lysine, arginine, histidine, ornithine, basic di- and tri-peptides, and cationic antibiotics such as imipenem (n-formimidoylthienamycin) and other penems and carbapenems (Tamber et al., 2006).  The 3-d structure and drugs transported are known (4FOZ; Parkin and Khalid 2014).  OprD is the vitronectin receptor. Vitronectin enhances P. aeruginosa adhesion to host epithelial cells and thereby enhances virulence (Paulsson et al. 2015).  Loss promotes carbapenem resistance (Shen and Fang 2015; Cavalcanti et al. 2015).
