RESUMO
Most strains of Streptococcus mutans possess a 190-kDa protein antigen (PAc) on their cell surfaces, while strain GS-5 produces extracellularly a 155-kDa PAc protein. The pac gene of strain GS-5 consists of 3,477 bp and codes for a protein of 1,158 amino acids. One insertion of an adenine into the 3,469th, 3,470th, or 3,471st position from the start codon results in a frameshift mutation at codon 1157 with subsequent termination after 3 additional codons.
