Abstract |
Among the major bacterial secretions, outer membrane vesicles
(OMVs) are significant and highly functional. The proteins
and other biomolecules identified within OMVs provide
new insights into the possible functions of OMVs in bacteria.
OMVs are rich in proteins, nucleic acids, toxins and
virulence factors that play a critical role in bacteria-host interactions.
In this review, we discuss some proteins with multifunctional
features from bacterial OMVs and their role
involving the mechanisms of bacterial survival and defence.
Proteins with moonlighting activities in OMVs are discussed
based on their functions in bacteria. OMVs harbour many
other proteins that are important, such as proteins involved
in virulence, defence, and competition. Overall, OMVs are a
power-packed aid for bacteria, harbouring many defensive
and moonlighting proteins and acting as a survival kit in
case of an emergency or as a defence weapon. In summary,
OMVs can be defined as bug-out bags for bacterial defence
and, therefore, survival. |
