Summary
Parvulin (ppiC) family. [More information is available at EcoGene: EG10985]. SurA in Escherichia coli is a periplasmic peptidyl-prolyl isomerase which is necessary for the proper folding of outer membrane proteins including OmpA, OmpF and LamB. [More information is available at EcoCyc: EG10985].
