Abstract	The Tat protein transporter is found in the membranes of many bacteria and in plant chloroplasts. This highly unusual transport machine moves folded and often oligomeric substrate proteins across energy-conserving membranes. A recent paper reports the first use of a photo-crosslinking approach to dissect the early recognition events between the transporter and its substrate.
