Question

Proteins with an RTX motif share a common, ATP-dependent mechanism for this process. Proteins with an LPXTG motif that have undergone this process are then cleaved by sortases. (-5[1])A “passenger” domain allows some proteins to perform this process on themselves. An N-terminal motif containing a pair of “twin” arginine residues acts as a signal for this process in the Tat pathway. One system for this process (0[1])consists of a “needle” complex attached to a (*) basal body. H. pylori’s system for this process is evolutionarily related to the machinery for conjugation, (10[1])while Shigella’s system for this (10[1])process is sometimes called (10[1])the “injectisome” and structurally resembles flagella. For 10 points, some bacteria use “type III” and “type (10[1])IV” systems to accomplish (10[1])what process of exporting a protein from a cell, exemplified by the release of hormones from endocrine glands? ■END■ (10[1]0[3])

ANSWER: secretion [accept translocation; prompt on descriptive answers indicating that a protein is being moved across the cell membrane; reject any descriptive answers involving the membrane of something other than the cell, like “moving stuff into the endoplasmic reticulum” or “moving stuff into the mitochondria”]
