An insertion sequence, IS1562, was identified in a Streptococcus pyogenes strain of the clinically important M1 serotype. IS1562 is located in the mga regulon between the genes coding for the M protein and the C5a peptidase, both important virulence factors. The same or similar insertion sequences were found in most S. pyogenes strains, but the chromosomal location differed among isolates.
在临床上重要的M1血清型化脓性链球菌菌株中鉴定出一种插入序列IS1562。IS1562位于mga调控子中,在编码M蛋白和C5a肽酶的基因之间,这两种都是重要的毒力因子。在大多数化脓性链球菌菌株中发现了相同或相似的插入序列,但不同分离株之间的染色体位置有所不同。
