Burkholderia spp. that degrade phthalate have an ABC transporter-type phthalate transport system (OphFGH) and a specific porin (OphP) in addition to a permease-type phthalate transporter (OphD). OphFGH has a lower Km and higher Vmax than OphD, which affects how the bacteria grow. OphP is involved in both mechanisms of transport.
