>gnl|CDD|163239 TIGR03375, type_I_sec_LssB, type I secretion system ATPase, LssB family. Type I protein secretion is a system in some Gram-negative bacteria to export proteins (often proteases) across both inner and outer membranes to the extracellular medium. This is one of three proteins of the type I secretion apparatus. Targeted proteins are not cleaved at the N-terminus, but rather carry signals located toward the extreme C-terminus to direct type I secretion. This model is related to models TIGR01842 and TIGR01846, and to bacteriocin ABC transporters that cleave their substrates during export. Length = 694
