Conserved Protein Domain Family

cl30226: VpdB_C Superfamily 
C-terminal fragment of effector protein VpdB
This model represents the C-terminal fragment of the effector protein VpdB that binds the Legionella pneumophila Dot/Icm type IVB coupling protein (T4CP) complex which includes IcmS, IcmW, and LvgA. These L. pneumophila proteins are known to selectively assist the export of a subclass of effectors. The effector protein VpdB, like other L. pneumophila effectors VpdA, VpdC and VpdD, is a homolog of phospholipase A (PLA) patatin-like enzymes. However, VpdB does not appear to be involved in phospholipid metabolism. The structure reveals interactions between LvgA and a linear motif in the C-terminus of VpdB. This binding interface of LvgA also interacts with the C-terminal region of three additional L. pneumophila effectors, SidH, SetA, and PieA.
