Chaperone involved in the correct folding and assembly of outer membrane proteins, such as OmpA, OmpF and LamB. Recognizes specific patterns of aromatic residues and the orientation of their side chains, which are found more frequently in integral outer membrane proteins. May act in both early periplasmic and late outer membrane-associated steps of protein maturation. Essential for the survival of E.coli in stationary phase. Required for pilus biogenesis.3 Publications

The PPIase activity resides only in the second parvulin domain. The N-terminal region and the C-terminal tail are necessary and sufficient for the chaperone activity of SurA. The PPIase activity is dispensable for SurA function as a SurA protein with a deletion of the parvulin domains is almost completely functional in vivo. The N-terminal region and the C-terminal tail are also required for porin recognition.1 Publication

<p>The checksum is a form of redundancy check that is calculated from the sequence.
