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. |
