Crystal structure of EccC5 DUF domain of Mycobacterium tuberculosis
New insights into the domain of unknown function (DUF) of EccC 5 , the pivotal ATPase providing the secretion driving force to the ESX-5 secretion system.
DUF domain (aminoacids 1-417) N-terminal GP- Residues from PreScission protease cleavage site. Aminoacids 17-118 replaced by GSSG Aminoacids 167-198 replaced by GSG (numbered in pdb as 166a-166b-166c) Sample sequence scheme: GP-1-16-GSSG-119-166-GSG-199-417 GP+(aminoacids 1-123) - Unobserved region Aminoacids 275-283 - Unobserved region Aminoacids 311-315 - Unobserved region
