3.A.15.4.2
The tri-component complex including (1) EbsA of 125 aas, homologs of which are highly conserved and widespread in diverse
cyanobacteria but are not found outside this clade; (2) PilB, a 666 aa type IV fimbrial biogenesis protein, and (3) Hfq, a 70 aa host factor-1 protein. The tripartite complex of EbsA, Hfq, and the ATPase homolog PilB (formerly
called T2SE) are all three required
for the assembly of the hairlike type IV pili (T4P) appendages, for DNA
competence, and for exoproteome formation in addition to its role in
biofilm self-suppression (Yegorov et al. 2021).
