title: Structural heterogeneity of the streptococcal C5a peptidase gene in Streptococcus pyogenes.
abstract: The 3' ends of the genes for the C-terminal region of C5a peptidase from 15 Streptococcus pyogenes isolates were analyzed by PCR. Amplicons were found to differ in size. DNA sequence analysis revealed that the differences between PCR fragment sizes accorded with the number of R repeats in the C5a peptidase gene.
