The genome sequence of Lactococcus lactis revealed that the ycdB gene was recently exchanged between lactococci and enterobacteria. The present study of ycdB orthologs suggests that L. lactis was probably the gene donor and reveals three instances of gene transfer to enterobacteria. Analysis of ycdB gene transfer between two L. lactis subspecies, L. lactis subsp. lactis and L. lactis subsp. cremoris, indicates that the gene can be mobilized, possibly by conjugation.
乳酸乳球菌的基因组序列显示,ycdB基因最近在乳球菌和肠杆菌之间发生了交换。目前对ycdB直系同源基因的研究表明,乳酸乳球菌可能是基因供体,并揭示了该基因向肠杆菌转移的三个实例。对乳酸乳球菌的两个亚种——乳酸乳球菌乳酸亚种和乳酸乳球菌乳脂亚种之间ycdB基因转移的分析表明,该基因可能通过接合作用被转移。
