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 K(m) and higher V(max) than OphD, which affects how the bacteria grow. OphP is involved in both mechanisms of transport.
能够降解邻苯二甲酸盐的伯克霍尔德氏菌除了拥有一个通透酶型邻苯二甲酸盐转运蛋白(OphD)外,还具有一个ABC转运体类型的邻苯二甲酸盐转运系统(OphFGH)和一种特定的孔蛋白(OphP)。与OphD相比,OphFGH具有更低的米氏常数(K(m))和更高的最大反应速率(V(max)),这会影响细菌的生长方式。OphP参与两种转运机制。
