Expression level and cell-free extract activities of PirXI variants. Samples of 2 µg of crude extract protein prepared from cells grown on xylose medium were loaded on an SDS gel. The dominant bands at ~ 50 kDa represent PirXI. The expression level calculated by measuring the intensity of the bands is about 25% for both samples. WT: wild-type PirXI VA: V270A–A273G PirXI
