Polymorphic proteins of Chlamydia spp.--autotransporters beyond the Proteobacteria

Trends Microbiol. 2001 Dec;9(12):573-8. doi: 10.1016/s0966-842x(01)02234-x.


Gram-negative bacteria secrete a variety of proteins to the cell surface and beyond, a process with many inherent difficulties. An exceptionally widespread answer to these problems is the type V (or autotransporter) secretion pathway. By exploiting the data made available by bacterial genome sequencing, we have discovered that the previously described polymorphic proteins of Chlamydia spp. resemble members of the autotransporter family, and we suggest that they follow the same secretion pathway.
