CommentType III secretion systems translocate proteins, usually virulence factors, out across both inner and outer membranes of certain Gram-negative bacteria and further across the plasma membrane and into the cytoplasm of the host cell. This protein, termed YscF in Yersinia, and EscF, PscF, EprI, etc. in other systems, forms the needle of the injection apparatus.
