3.A.15.2.1
The pilin secretion/fimbrial assembly system. The PilB and PilT ATPases act antagonistically in Type IV pilus function in Myxococcus xanthus. ATP binding and hydrolysis by PilT are essential for T4P extension while ATP binding and hydrolysis by PilB are essential for T4P retraction. Thus, PilB and PilT act at distinct steps in the T4P extension/retraction cycle (Jakovljevic et al., 2008).
