Enterohemorrhagic Escherichia coli
OmpT regulates outer membrane vesicle biogenesis.
Obviously, BL21 (DE3) showed the highest expression in comparison to Rosetta-gami and SHuffle T7 possibly due to its protease deficient genotype (lon,
OmpT).

OmpT outer membrane proteases of enterohemorrhagic and enteropathogenic Escherichia coli contribute differently to the degradation of human LL-37," Infection and Immunity, vol.
It is worth noting that, among the 16 VFs detected in phylogroup B2, two were exclusive to that group (sfaDEand cnf1), and six others (papC, irp2, kpsMT II, hlyA,
ompT, and chuA) showed a statistically significant association (P [less than or equal to] 0.001) with that group (Table 1).
The host strain has neither lon nor
ompT mutations (9), and no protease inhibitors or nucleases were used in the purification.

The signal peptides Bla, gill, LPP, npr,
OmpT, TolB, TorA, and TorT were excluded due to D-score lower than 0.5 and further analyses were performed on the remaining signal peptides.

Moreover, this strain possesses a deficiency in the Ion protease and lacks
ompT outer membrane protease.
