The crystal structures of two members of the SF1 family of helicases, Rep and PcrA, and one member of the SF2 family of helicases, the HCV RNA helicase, have recently been solved. These structures illuminate the roles of the conserved helicase motifs in catalytic function and offer clues as to how these proteins can translocate along DNA.
解旋酶SF1家族的两个成员Rep和PcrA以及解旋酶SF2家族的一个成员丙型肝炎病毒（HCV）RNA解旋酶的晶体结构最近已被解析。这些结构阐明了保守解旋酶基序在催化功能中的作用，并为这些蛋白质如何沿DNA移位提供了线索。
