Figure S1 - Region Specific and Worldwide Distribution of Collagen-Binding M Proteins with PARF Motifs among Human Pathogenic Streptococcal Isolates

Prediction of coiled-coil structures in PARF-positive M proteins. Coiled-coil structure prediction for the N-terminal sequences of the indicated PARF-positive M proteins is depicted as P-scores vs. the amino acid position relative from the PARF motif with the first amino acid of the motif being position 1. Scores below 0.025 indicate a coiled-coil structure. The position of the PARF motif is highlighted in light grey.

PARF阳性M蛋白的卷曲螺旋结构（coiled-coil structure）预测。
针对所标注的PARF阳性M蛋白N端序列的卷曲螺旋结构预测，以P评分（P-score）为纵坐标，相对于PARF基序的氨基酸位置为横坐标进行绘制；该基序的首个氨基酸被定义为位置1。
当P评分低于0.025时，即可判定存在卷曲螺旋结构。
PARF基序的位置以浅灰色高亮标注。
