Mfa5-2 is a newly identified structural component of Mfa1 fimbriae in Porphyromonas gingivalis.
The study highlights the structural diversity of Mfa1 fimbriae, suggesting complex assembly mechanisms.
Assessment focused on the expression of Mfa5-2, a high-molecular-weight component in two strains of P. gingivalis.
Findings offer insights that may enhance understanding of pathogenic mechanisms in Porphyromonas gingivalis.
Abstract
Mfa5-2 is expressed as a high-molecular-weight component and integrated into the Mfa1 fimbriae in P. gingivalis EM3 and 1439. These findings revealed previously unknown structural diversity of Mfa1 fimbriae.
