Structure
YbgF is a periplasmic protein with an N-terminal coiled coil domain (NTD) and a C-terminal tetratricopeptide domain (TPR), both of which are autonomous[1]. As seen in the 3D structure 2WZ7, the NTD forms an elongated trimer which is connected via a flexible linker to the TPR trimer, as seen in 2XEV. This connection can be cleaved by proteases[2].
Function
YbgF is a periplasmic protein which interacts with the C-terminal domain of TolA (TolAIII) during the import of colicin A into the cytoplasm[3].
