Pex 1和Pex 6是过氧化物酶体从头生物合成所需的2型AAA+ ATP酶。Pex 1和Pex 6的突变是人类过氧化物酶体生物合成障碍的大多数最严重形式。在这里,我们表明,ATP依赖的复合物的Pex 1和Pex 6从S。酿酒酵母是具有交替亚基的异源六聚体。在Pex 1/Pex 6复合物中,只有D2 ATP酶环水解ATP,而D1环中的核苷酸结合促进复合物组装。Pex 1的ATP水解与Pex 6的ATP水解高度协调。此外,Pex 15,Pex 1/Pex 6募集到过氧化物酶体所需的膜锚,抑制Pex 1/Pex 6的ATP水解活性。
Pex1 and Pex6 are Type-2 AAA+ ATPases required for the de-novo biogenesis of peroxisomes. Mutations in Pex1 and Pex6 account for the majority of the most severe forms of peroxisome biogenesis disorders in humans. Here we show that the ATP-dependent complex of Pex1 and Pex6 from S. cerevisiae is a heterohexamer with alternating subunits. Within the Pex1/Pex6 complex, only the D2 ATPase ring hydrolyzes ATP, while nucleotide binding in the D1 ring promotes complex assembly. ATP hydrolysis by Pex1 is highly coordinated with that of Pex6. Furthermore, Pex15, the membrane anchor required for Pex1/Pex6 recruitment to peroxisomes inhibits the ATP-hydrolysis activity of Pex1/Pex6.
