DNA 重排允许细菌调节基因内容和表达。在幽门螺杆菌中,cagY 含有大量直接 DNA 重复序列,编码(IV 型)细菌分泌系统的表面暴露亚基。检查涉及 cagY 重复序列的潜在 DNA 重排表明重组事件总是产生框内开放阅读框,从而产生替代表达的基因。在个体宿主中,幽门螺杆菌细胞群包括由于预测的框内删除或重复而产生大小不同的 CagY 蛋白的菌株,并且引起最小或不引起宿主抗体识别。使用重复DNA,幽门螺杆菌在保守细菌分泌系统的暴露于宿主的亚基中进行重排可能允许一种新形式的抗原逃避。
DNA rearrangement permits bacteria to regulate gene content and expression. In Helicobacter pylori, cagY, which contains an extraordinary number of direct DNA repeats, encodes a surface-exposed subunit of a (type IV) bacterial secretory system. Examining potential DNA rearrangements involving the cagY repeats indicated that recombination events invariably yield in-frame open reading frames, producing alternatively expressed genes. In individual hosts, H. pylori cell populations include strains that produce CagY proteins that differ in size, due to the predicted in-frame deletions or duplications, and elicit minimal or no host antibody recognition. Using repetitive DNA, H. pylori rearrangements in a host-exposed subunit of a conserved bacterial secretion system may permit a novel form of antigenic evasion.
