The complete nucleotide sequence of the ami locus of Streptococcus pneumoniae revealed the presence of six open reading frames, amiABCDEF. The predicted Ami proteins are probably involved in a transport system. The AmiA, C, D, E, and F proteins exhibit homology with components of the oligopeptide permeases (opp) of Salmonella typhimurium and Escherichia coli. Intriguingly, the AmiB protein is homologous to ArsC, a cytosolic modifier subunit of the anion pump encoded by the arsenical resistance operon of the R-factor R773 from E. coli. Data are presented which indicate that Ami is indeed a transport system.
肺炎链球菌ami位点的完整核苷酸序列显示存在六个开放阅读框，即amiABCDEF。预测的Ami蛋白可能参与一种转运系统。AmiA、C、D、E和F蛋白与鼠伤寒沙门氏菌和大肠杆菌的寡肽通透酶（opp）的组分具有同源性。有趣的是，AmiB蛋白与ArsC同源，ArsC是由来自大肠杆菌的R因子R773的抗砷操纵子编码的阴离子泵的胞质修饰亚基。所呈现的数据表明Ami确实是一种转运系统。
