ESX-1 secretion-associated protein EspB, PPE domain
This entry represents the PPe domain of ESX-1 secretion- associated protein EspB, a member of the PE/PPE family and the only one described to date to form higher-order oligomers [1-3]. It contains PE (Pro-Glu) and PPE (Pro-Pro-Glu) domains, and a C-t ...
This entry represents the PPe domain of ESX-1 secretion- associated protein EspB, a member of the PE/PPE family and the only one described to date to form higher-order oligomers [1-3]. It contains PE (Pro-Glu) and PPE (Pro-Pro-Glu) domains, and a C-terminal domain, which is processed by MycP1 protease during secretion. EspB oligomerises into a cylinder-like heptamer through its N-terminal domain, that form channel-like structures [1-3].
The ESX-1 secretion system is an important virulence determinant in Mycobacterium tuberculosis. ESX-1 secreted protein B (EspB) contains putative PE (Pro-Glu) and PPE (Pro-Pro-Glu) domains, and a C-terminal domain, which is processed by MycP1 protea ...
The ESX-1 secretion system is an important virulence determinant in Mycobacterium tuberculosis. ESX-1 secreted protein B (EspB) contains putative PE (Pro-Glu) and PPE (Pro-Pro-Glu) domains, and a C-terminal domain, which is processed by MycP1 protease during secretion. This domain represents the PE domain located at the N-terminal region of EspB which carries the conserved YxxxD/E secretion motif [1].
